I pressed 1 and went through to an operator who said my number had a case looking for "fred flintstone" ... I asked him if he thought I was stupid and he said he'd take my number off the call list

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.

Called several times... I missed the call but they left no message.

by the way, thanks Jack for your research and info. it helps to know the truth.
also, if anyone can find a photo of this criminal it would be a good thing to post it all over the web...
although now that i think of it, i would not be surprised if someone actually stole Deanna Lynn Natale's identity and is doing all these crimes in her name. Otherwise how else can you explain that the police have not yet arrested her?
if so I petty the real one...

I called them back on their 866 # from a payphone, so nothing can be tracked or charged back to me.

When they answered, I just said I was calling in response to their message, then hung up.
I called again a minute later, and started a conversation then just left the phone hanging.
Call again, speaking in some made up language.
Call again, and I asked the guy how annoying is it to get nuisance phone calls?

Repeat until you get bored. It's great fun and it costs them money every time you call.

me too, they have called several times. I owe nothing to anyone. These idiots are totally phishing and scamming. A "real" communication has information about you, doesn't "ask" for it. Hang up and report them to all and sundry.
