I have used QuiBids with fairly successful results... that is until three of the gift cards I received were INVALID. Attempts to contact customer service by e-mail have gone unanswered. I contacted customer service by phone and was assured that the cards would be activated. Three days later and nothing. I posted a comment on the QuiBids FaceBook page detailing my experience and providing a link to the Oklahoma State Attorney General's website for complaints (QuiBids is based in Oklahoma). Within minutes, my post was removed and yet they don't have time to answer e-mails or take care of paying customers?
