Iphone 4 unlock from AT&T

The last time i talked to someone at AT&T they told me i would get my email by today 4/17...(bs)
I called them just now and they have so many request that they are running behind and told me for sure i would have my email within 5-10 business days. They started on sunday 4/8 to unlock and i called monday 4/9 at 1pm...AT&T sucks! I want to use my damn phone...ugh! If i dont get my email im going to just buy the damn rsim. Which is supposed to be out soon, maybe not because that team sucks also, they might as well work for att because they say the same shit every week. "were so close to having the unlock, we need another week"
