AT&T Store

We went in to purchase new phones, since our old ones do not even have texting. We transferred over from Verizon due to coverage issues. When I went in to purchase an LG Xpression, it was marked down for half off (as a mail-in rebate offer). I looked at the offer and it said that it didn't start until the next day, so I asked the rep about it and he said it wouldn't be a problem. I purchased the phone and sent in the rebate but received a letter saying they would not honor the deal because it does not fall within the specified dates. Now when I call the store back, I am sent on a rather large and complicated gauntlet which ultimately leads back in on itself. I cannot use the "I'm not on a touch-tone phone" trick, nor can I use the "dial 0 for operator" trick. When I finally try the gauntlet for the 4th time, I pretend I am going to purchase something new and I actually get through to the store, but it only rings 3 times before leading back into the phone gauntlet. Needless to say I am displeased with their lack of professionalism and inability to address customer concerns/needs.
