You don't know the half of it as far as Cingular is concerned. I worked for them for two awful months, helping people who called in about their bills. There were so many situations where it was clear to me that a REP had screwed up on this person's account, costing them more, and I was not allowed to refund it back to them. A lot of Cingular agents are as crooked as can be. When a person goes into a store to renew their contract, I can't tell you how many times the salesperson would give them a whole new account, in order to gain the commission, and the person would call in and not understand why their bill was all screwed up. It was such a mess. I encounted multiple situations where on the bill, the person was being given no NEW minutes for that month, it just withdrew from their bucket of rollover minutes, making it more likely for them to go over the minutes, which costs a rip-off of .45/min on most plans. Perhaps it was an innocent computer error, but I complained about it multiple times, and I never saw it get fixed, at least not while I was there. The worst though, was knowing people were getting overcharged through no fault of their own (such as the guy who had a rep change his plan in the middle of his billing cycle, which cut his bucket of minutes for that time in half, causing a huge overage, of over 400 dollars, and she didn't bother to tell him that's what would happen, and he got a huge shock when he got his bill. I argued with mgmt for two days over that one and they finally agreed to give 50% of it back to him. Whoop-de-doo.
Quitting was such an enormous relief. I had AT&T for years, but I've switched to T-Mobile, because I will not give any business to that awful company. It's too bad they took over AT&T, because I was always very happy with them before.
