ATT Reward Center - 5 months later still no reward

I submitted a rebate form to the ATT Reward Center on 4/4/09 after upgrading my internet to high speed internet. This was supposed to give me a check for $79.99 to offset the purchase of a modem that I got at the ATT store. I filled out all the forms including the serial number of the modem and mailed it in promptly. It said I'd receive a check in 4-6 weeks. A month went by and I called in to check. They said they got my form but it was missing the serial number. The rep said to just read it to him and he'll re-enter it. I did so. The check he said would be in my mailbox in a week. Another month went by. I called again. They said they need me to fax the serial number in to them on a piece of paper. Even though this is the THIRD time I've given them this info, I fax it in along with a copy of the orginial serial number on the box. They said they got it and the check will be there in a week or so. Another month goes by. I call again. They apologize. They said they said it's still processing. Another month goes by. Now it's almost FIVE months since I submitted it.

This is a scam. I think they have no intention of paying and just hope consumers will give up . Don't get taken by any of their rebate offers. It's not worth it.
