Offerwire = Awful Liars
This company signs you up for service with Comcast. It sells you a cable modem and a wireless router and offers you a rebate if you send them several items of information, proofs of purchase, and documentation, including a copy of 2 months of your Comcast bill.
Even if you pay Comcast for two months and send Offerwire a copy of the bill, it claims it cannot "Honor" the rebate because it does not have a copy of the bill. Failure to honor the rebate offer is a great choice of words because it is obvious this company has no intent to operate in an ethical fashion. Instead, it will stonewall you until the offer expires.
Stay Away from Offerwire and Bridgevine. These companies are just scam artists. They have no intention of honoring their rebate offers. The sooner they are out of business, the better it is for the general public. Shame on Comcast for partnering with these unscrupulous losers.
