Purchased voucher for Stride Stand up paddleboarding, booked lesson well in advance with a friend so we could coordinate schedules/babysitters, received confirmation 3 days prior to lesson. We showed up to location early as instructed and no one was there. Finally left about 10 minutes after lesson was supposed to start and called vendor. He returned call the next day saying he had sent an email changing the location. My friend and I never received that change and that is because he typed the email address wrong. We asked him for a refund and he said okay we'd have to go through Livingsocial. We applied for refund through LivingSocial and they denied saying we were outside of the window. We called and explained that this was the vendor's fault and not ours and we shouldn't have to book another lesson again and waste more of our time. LivingSocial hasn't returned our phone calls/emails since then. Shady operation at best. Yes, they're hooking you up with deals, but beware if anything goes wrong they will NOT have your back. We're currently processing refund through our credit cards!
