I'd give a zero star of I could. I bought a voucher for a 1 night stay in an hotel. The voucher it's impossible to redeem and I have been trying with two different phones one computer desktop and every possible browser on it. It simply doesn't work. The hotel won't accept my booking even if showed them the confirmation because they said they can't access the money if the voucher isn't activated. I tried to use living social refund page, but "strangely is unavailable at the moment".
Stay away from this scammers.
