Do NOT rent from these sham artists!

When you have been tricked, who would give 1 star. Booked a Seat Ibiza on 14th/10. The local supplier was Click-Rental. Price was about 68 Euros for 8 nights & I paid the premium insurance so came to 124 Euros in total. Also selected the full-2-full fuel option. Received email booking voucher same day & email to add flight details that I has already added, but did it again anyway. Firstly Click-rental made me pay for a full tank + 31 Euros filling charge!! It came to 127 Euros. I filled the car up on less than 70 Euros.
Total sham & they would not honour what I had booked. Worse was to come. DYS then proceeded to charge me twice for the car. It came to 245 Euros. Their flimsy excuse was I had modified the reservation as I re-added the flight details. Citing the car had doubled in price. Again checked the price when I got home & yes of course is the same 68ish Euros I originally paid. Would hate to see others get tricked by this outfit, go somewhere else of repute. Received one email from them & nothing since to respond & put this right, customer support does not exist. Trying to go via bank for refund as paid on CC.
