This company is a scam. We saw an ad through Costco and visited the kiosk for the deal on an upgrade through AT&T. After an hour of signing documents and activating the new phones, the customer service rep informs us that our phones are not eligible for the upgrade. It took an additional 2 hours to re-activate our old phones.3 hours of time wasted. The advertisement contained nothing about which phones were eligible for the upgrade. The customer service rep said it was his colleague’s fault for not checking on our phones. Costco took no responsibility despite the fact they contract with this joke of a company. Avoid at all costs.
