I was contacted by ACM last Saturday (June 19, 2010) by phone. They'd 'tried to contact me by mail' but got no response - or return (I'm no longer at the address they had listed (but my other addresses are on my Credit Report)
They said I owed a rather large amount on a Bank of America Credit Card from June 2001 - and would take me to court on Monday (Convenient - they 'found' me on the weekend) unless I could pay.
I NEVER had the card - so: never received statements, and of course never paid. I have the records to show. I told them that and asked them to send over Documentation before I paid, and a Mr. Santos said that they couldn't do that - as it would be presented in Court in Monday.
As an aside: Their receptionist didn't sound professional - Mr. Santos didn't sound professional - though he did have a lot of facts (a very scary idea) as to other cards that I had (of course he could find those on my CR)
The card is listed on my CR - but, as it never existed, I don't know how it got there: unless ACM managed to put it there.
So - as above, if ACM calls - follow the advice in the above responses
