Mr.Oleary from gatestone collections.  They seem to have several numbers they call you from +1 800-256-8349)

No message left......call back....they just answer with the persons name and saying customer service.Hello Gatestone POS.......thank you for calling my house at 8:19 am.  This fine Saturday morning!

when these guys call, you can ask for the agents license number so you have a reference to who called you if there is a need to verify it for what ever reason.  If they refuse to give you the agents license number its a violation of regulation and you can report them.  this is just proof you are talking to a legitimate agency.

I have received a call from (416) 969-2186 (extension 6201) today. The person on the other side said that her name is Donna T and that she is telephoning me for business matters. How did she find out my telephone number and my name? Who was she?

This number keeps calling.
