I think there is more than just the $20? =/

At&t is a scam artist. Avoid it at all costs. I was told I would receive a rebate in 4-6 weeks for the modem I purchased 2 months ago. The sales representative at the store filled in all of the information on the rebate form and informed me that all I had to do was fill out my address and mail it in. I never received the rebate. When I called to find out why not, I was told, well even though we received all of your paperwork, we canceled your rebate because the 'skew' number was not written on the form. After complaining and threatening to stop paying my bill altogether I was finally transferred to a supervisor who admitted that the skew number was on the receipt I provided, but that they had not bothered to input it into their system so that I could receive my rebate. I may receive the rebate in another six weeks! Everyone else who purchased a modem at that store (and likely all over the country) who does not call to complain will not receive their $100 rebate. This is an organized scam for At&t to steel millions of dollars from its customers. Someone should sue them for false advertisement and theft. Avoid At&t at all cost.
