This place really is a scam.
I have known about them for a long time, I knew them when they were econo wireless.
They will offer you great prices by cheating the cellular providers and you (example: they sell you a certain phone (plus contract) that doesn't have a rebate deal yet, then they tell the cellular provider that you bought a different phone that does have a rebate deal, they will take your upc / "boxtop", to use in future with some other customer, and off you go).
They will also claim insurance claims if you bought insurance and leave you with the deductible, they tried it with one of my friends w/ att. (one day, att calls to verify the insurance claim, att even told my friend that the shipping address was back to the store!)
They have been able to get away with this for so long because they keep changing company names. if you've pasted by, you know the name keeps changing. the are/ were also called "Eternal wireless" at some point.
beware, if you did sign up through them, call the cellular company (att, tmobile, etc) and ask for some kind of security code to use.
They obviously make money from contracts, so i'm not surprised that they will falsely upgrade your contract, probably collect any credit for new phones, and leave you with a basically never ending contract.
