Disgusting service and useless wikideals

Utterly disgusted by the way they do business. Myself and sister purchased 2 vouchers from wikideals in December and January. We immediately contacted hotel to make a booking for weekend in March. After numerous calls and disgusting service the front desk keeps on telling us they haven't received any feedback as to availability. How is it that from December no one is able to assist us to make a booking in March. After numerous telephone calls they are now telling us that there is no availability for the dates we requested in December already. They simply tell us they only allow a certain amount of wikideals per month... Why is this not declared in the terms and conditions? Why is it that ive been striggling for 3 months to make a simple booking only to be told now there is no availability... They also acnnot addist with a refund??? This is utterly disgusting service from the hotel and wikideals as they are robbing us of our money and they jist pool up there shoulders saying they cannot accommodate you... Why is this deal/offer still on the wikideal website if there is no availability. I purchase the voucher in December... Booked in early January... And still thry keep on telling you "the dates isnt out yet we will stay in contact"... And believe me they dont stay on contact at all unless you follow up. I am disguster by this!!!!
