we booked a hotel through zen hotels and received a fully paid voucher for the hotel we booked,After 3 days of our holiday we were notified by our hotel that they still couldnt find our booking.I emailed zen hotels and they said they couldnt understand why they couldnt find it.The hotel was very good and after still not being able to find the booking,and numerous emails causing me lots of stress,the company Zenhotels admitted that due to a technical error on their part,they had booked us into a differant hotel,,a hotel i would not stay in.They told me i had to move hotels or pay the hotel i booked myself again,,which had more than doubled in price..I refused numerous times,,but they would not pay,In the end we had to pay again,,it ruined our holiday and i am now out of pocket.Theyhave now refunded me the cost i originally paid, but obviously this was not the price we had topay again,, i have sent numerous complaints to their dept. but as yet i have not had a reply
