I purchased 2 tickets from living social for pre season Dallas Cowboys vs Vikings game at AT&T stadium. Paid via credit card 2 months ago and received 2 vouchers. Game day was today 8/29/15 at 6pm. I arrived at will call at 6pm and was told the voucher was not valid or honored by AT&T stadium and they have no affiliation with living social or via tix online. After almost an hour speaking with will call and a box office manager they advised I should contact living social because the vouchers provided are not honored. They only accept tickets from ticket master. Called living social and of course they were closed. Now I have to wait to speak with them to refund my money! They ruined my day. Never again!
