I also received numerous calls from this number.

Voice recording, reference to a law office, paperwork and requesting that I call them immediately.

No case number just annoying calls and voice mail messages.

I have been getting these calls...they tend to make a person a little paranoid...but kudos to you Jack for all of your research.  I live in Nova Scotia, and read all of your response.  I work at a law firm and everybody should know that law offices do not try to reach their clients with a really lame automated service, asking you to call them back.  Same is true about how Jack spoke of receiving important legal documents, a Statement of Claim is served on people by law firms usually through a process server.  These idiots need to get a life and stop trying to scam people.  I almost got sucked in by another scam (one to lower your credit card interest) and felt like a complete idiot...so now I'm really ticked off at all of the annoying calls, I want to get an airhorn to blast in the phone, if it was a real person calling me, I'd be all set!

Natale law office works typically for a debt acquisition/collection agency

They attempt to intimidate people into paying statute barred and/or alleged debts.
if they had recourse you would have been served.

Send a registered letter to Natale Law office telling them not to call as per the collections act.
log all calls after they receive the letter and file a complaint with consumer protection services against them.

it wouldn't hurt to let them know you also intent to bill THEM for each unsolicited call.

it wouldn't hurt to note you will hold them responsible for harassment if this is not conveyed to future acquisition companies.

if the file with your information is sold, they will typically start harassing you all over again

Being a law firm (and i use the term loosely) they are well aware that this is harassment.
I received a draft statement of claim from them regarding an alleged debt and was informed by the court that this is a prohibited practice. They are either to file a claim or not, sending out draft claims is an attempt at intimidation.

From the Ontario Ministry of Consumer Affairs Web site
The Collection Agencies Act prohibits collection agencies from doing certain things.

The Ontario Ministry of Government Services consulted the collection industry to develop a standard to be followed by all collectors. Having a standard also allows the public to have a better understanding of what collection agencies can and can't do.

The regulations forbid collection agencies from:

contacting you until six days have passed from sending you written notice of the following: • the name of the creditor • the balance owing • the name of the agency and its authority to demand payment
continuing to contact you if you did not receive the notice unless a second copy of the written notice is sent to an address provided by you, and then contact may only be made six days after sending notice;
contacting you if you send a registered letter to the agency saying that you dispute the debt and suggest the matter be taken to court;
contacting you if you or your lawyer notify the agency by registered mail to communicate only with your lawyer, and you provide the lawyer's name, address and telephone number;
contacting you on Sunday, except between the hours of 1 p.m. and 5 p.m., and on a holiday;
contacting you other than by ordinary mail more than three times in a seven-day period without your consent, once the agency has actually spoken with you;
using threatening, profane, intimidating or coercive language, or using undue, excessive or unreasonable pressure;
continuing to contact you if you have told them that you are not the person they are looking for unless they take reasonable precautions to ensure you are that person;
giving false or misleading information to any person;
recommending to a creditor that a legal action be commenced against you without first sending you notice;
contacting your employer except on one occasion to obtain your employment information, unless your employer has guaranteed the debt, the call is in respect of a court order or wage assignment or if you have provided written authorization to contact your employer;
contacting your spouse, a member of your family or household, or a relative, neighbour or acquaintance except to obtain your address and telephone number unless the person contacted has guaranteed the debt or you have given permission for the person to be contacted.

Received a letter in the mail from Natale Law Offices stating I owed ROGERS money, yet I have not been with ROGERS since I paid off a bill 4 years ago. I phoned ROGERS and they said there was nothing owing under my name and that the payment was made in full 4 years ago. I then called Natale Law Offices and spoke to a man who barely spoke english, when I told him my ordeal he put me on hold, when he came back to the phone he said "How can I help you?" lmao, the guy had no idea what was going on, so I got transfered to a girl and she said for me to email or fax her the details. I said I would rather speak to ROGERS and she then said that is fine but to make sure I get a letter from ROGERS stating I do not owe. I then told her that she can mail me as many letters as she wants because she won't be getting any money from me.Somehow this company is stealing or buying information. Whether it's people who actually do owe money or people who do not.I bet it's an extra cash grab for the government.Anyways, she can blow me.

Call ID: (905) 413-8624. Voice message identifies caller as 'Natalie Law Office' and issues an order to call back to this number: 1-+1 866-262-9537. Doesn't identify the person the message is for, and uses an authoritarian tone to impress a sense of urgency and obligation.I don't imagine any law office will ever call you to tell you about a legal issue. They'll communicate in writing, that's the only way to make it official (for the record) in legal proceedings.Disregard and phone your police dept. to report the annoyance.
