When I signed up for high speed internet via internet, I was told I would be directed to a $79.95 modem rebate site after giving my information to have modem professionally installed. While I was giving my address to the "chat" I asked about the rebate and the Comcast rep said he didn't have any info about that and then the screen closed. When I phoned Comcast I was told the installer would have the form. He didn't and did not know anything about it. He contacted Comcast without results. I have contacted Comcast via phone, via internet, the installer called them and no one can give us any information. I have printed out a modem rebate OFFER from the Comcast/broadband/offers.com website. This cost me $99 and no rebate in sight.
