I also got the call and told them don't call me again or ill call my lawyer and she told me not to threaten her!

I got a call from them too, in Toronto.  I didn't answer. They left no message.  Can't be a collection agency as I don't have anything that would have gone into collections.

They keep calling me, not telling me who they are. They ask for me by name, but then just want me to read off my mailing address to them. I continue to ask them what my address is and I will confirm but they say they can not. So i guess it may even be a scam

place is a collection agency called CBB

dont know who this is any eles get them calling ???
