Turned up at our appartments at 3am booked through travelup to find they had no booking for us though we had confirmation docs with us. Luckly the hotel called around an managed to find out we had been booked into acompletely differnt appartments at the opposite side of Kos town. Called travelup everyday of our holiday and promised they would sort it and call us back. No-one ever did We have raised 3 complaints by email. Still a month later no-one has contacted us. When I've asked for their complaints procedure, i was told i had to email customer services Disgusting customer service Had the manager from the apartment not managed to find out where our booking was, we would have probably ended up slepping on the beach Also i have checked they are not not registered with ABTA and ATOL only covers flights DO NOT BOOK WITH TRAVELUP
