I keep getting these calls as well.  I don't answer if I don't recognize the number so it goes to voicemail, where of course it is a male voice on a recording stating that it is a law office(didn't name the law office) and it is an urgent matter.
First off, I went to school for the legal field and if a lawyers' firm is calling, they will leave the name of the firm and the contacts name.  I find that this is totally ridiculous.  I have to agree with the aforementioned, Send me proof of moneys owing and I will deal with it that way.  I give no pertinent information over the phone especially when I am not sure who it is.

I also received a call from these people, they called from this number, but wanted me to call them back at 1-+1 866-653-1524 (also look up this number), you can try to call back any of these numbers and all you get is an answering machine, (from other people's comments) they try to tell you that you owe money, and that you MUST send it immediately to avoid being taken to court, even if you don't owe anything, her company will harass you until you give in.BTW the number belongs to Natale Law Officeher home phone number is Deanna Lynn Natale27 Idleswift DriveThornhill, OntL4J-1Kp(905) 882-7684Her Office isDeanna Lynn NataleSuite #405 8133 Warden AvenueMarkham, OntarioTel: (905) 413-8748Fax: (905) 479-4071you can try the other numbers,

this people ARE OUT OF THEIR MIND.they really need a life do they have one?I htink we should never answer or call them back they will go to hell anywaythey are fishing for information do not give them your really name, do not call them from your home they will have your name in their stupid system and they will sale your information the markers.

Natale Law Office, Toronto. They also send out a fake Court Summons document.

Blatant misrepresentation...caller advised this was a "law Office" (no name mentioned)....in reality a credit card company. I CONSIDER THIS A FRAUDLENT ACT....as well as harassment.  Would like action taken against such malpractice.

Repeated calls.  Fake!  Do NOT Answer!
