I am furious because I am just another victim of this scam.
On June 25, 2009, someone from SILV Communication called and said she was from AT&T. She said they had a better plan than what I was having with AT&T (she knew exactly what I was paying under the AT&T plan for local and long distance). I said since she's with AT&T why couldn't they just go ahead to make adjustment to my existing plan; she said it was the procedure they had to take...
During the conversation, I repeatedly asked her if this was some kind of switch-of-account scam, she assured me "no; it is the same company (At&T)" . When I asked for her telephone she gave me 800-222-0400. As soon as I hang up with her, I called that number: it was an At&T number.
Yesterday, I received my AT&T bill and it included one separate bill from USBI (billing on behalf of SILV Communication). Not only was I billed by SILV Communication, I had to pay an "early termination fee" of $87.67 and $95.00 for long distance (it was $10.00 flat before) from AT&T.
Today, I called AT&T and talked two customer service representatives for over two hours. They were very helpful to get things straightened out. But I have to watch for another one or two billing cycles to see if USBI/SILV has in fact taken my number out of their list.
I also checked the BBB ratings of USBI and SILV Communication. Both have "F" the lowest.
Be careful! There are thieves out there!
