I also had this happen with a slight twist. A month after I got my 7105t, I got a bill worth $3K (from using text, IM, PIN and email alone, no phone calls) because the rep didn't do their job and put the charge on my bill when it was someone else's. I called them because of them having a habit of not getting payments.
Anyway, the rep asked me who I was and I told her. Gave her all my acct info, etc. Turns out someone in accounting had the bills screwed up like I said. I ended up only having to pay $330 (the cost of the 7105t plus the end of the previous bill...I switched from a Sidekick 2 to the BB).
