What a nightmare to deal with groupon customer service, seems like all of them working abroad and dont know what customer service is. My provide doesnt have much availability, cant reac h on line and the booking link is broken, so i tried for several days and now asking to refund my groupon and all they say it out of cancellation window. I used groupon service in UK for 7 years and never encounter such poor horrible service. Be aware, never will do it again.
