Cingular Wireless ripoff Dishonesty in rebates Hollywood California

I bought my cell phone in late September and sent in all my papers for the rebate (the saleslady had me do everything with her and said I was ready to go). It is now February and I still haven't received my $75 rebate.
I also had to change my rate plan due to them charging me around $250.

I saw my summary sheet, as I disagreed (I rarely talk on my cell) and I saw that they'd been charging me for the minutes I'd used before my minutes were up since I went over my minutes on calls that weren't supposed to be charged, as they were with other Cingular customers (to illustrate: I had 450 minutes and I used them on the calls that weren't with Cingular customers, as I knew those were the ones that would cost me.

Then, after my minutes were up, I'd only call my friends who had Cingular, so they wouldn't charge but I got my bill and they billed me for the minutes I'd used before my 450 minutes were up since those were the ones that would cost me more money, which is a total rip-off!)
