I bought a voucher for wheel alignment at Sears. I went to use it, but it said voucher had been redeemed. The store told me to call Living Social to get it resolved. When I tried to contact them, I could not find a phone number on there website, only email. I searched the web and found a couple numbers that said they were customer service at Living Social. When I called them, it was non existing numbers. When I emailed them, they responded back a couple of times, then blocked me from emailing them. I am in contact with my credit card to cancel the transaction. DO NOT BUY FROM ANYBODY THAT DOES NOT HAVE AN ACTUAL CUSTOMER SERVICE CONTACT NUMBER. Living social is a scam!
