Hi, Reference number: US600832390 I made reservation for the 31 May to rent a bigger car of 7. I called in advance 4 days before picking the car to change the dates to 02 june and return 03 June. The lady from your customer support told me all was fine and i should receive a confirmation mail the next day. As i did not receive this confirmation mail i sent an mail to customer services asking what had happened. The mail i then received back said no action was taken on your requested changes. Lord! My second attemt call to customer services, i request the changes once again and tell them about my previous call once again they tell me all is changed now. The lady from your customer services confirms all is fine now and all will be fine and i should use the same confirmation number, what seems weird and wrong to me. I had to trust her because as i had no choice, even at this time her tone on phone changed. She wanted just to get rid of me, due to all my questions and the clarifications i need answers to. I ended up trusting this woman from your customer servives (what was i to do?). The day of pickup came that's when the diserstar began. The address for pick up was wrong and we went looking for the place in more than an hour asking around and nobody knew anything. Am having my 6 visitors waiting (note this). After a long wait on phone to get in touch with ACE, the car renting offices, the customer services note me that the adress we had was very old more than 1 year ago. We then drove to the this new adress..note that you customer serves was is closed during weekends. When arriving to ACE offices i handed the voucher and it was a non exicting. The voucher for the new dates that was confirmed on phone was non existing instead, there was no show on my first booking for 31 May, which was to be cancelled from your offices. To me this seems as your sytem does not work together with ACE sytem plus this lady at ACE had never heard about holidaycar. How many mistakes can you guys make in a reservation...in this case i think your customer services would at least have called to check with ACE if there was a car for good service, instead of confirming something out of the blue. Ace said this is normally how other companies work. Truely you guys are bluffed me with my reservation and time as well! Shame on you guys! Unfortunately ACE did not have any cars for 7 that day so we ended up making a whole new reservation which cost us bubbel the price since it was last minut and we also ended up waisting more than 3 hour on your so called bluff reservation and confirmation having 6 people waiting. You guys are a joke! I have already started sharing my story and will keep on since this is awful. NEVER EVER HOLIDAYCAR and i do not want to receive anything advertisning on my mail since its all junk. Thank you for reading !!! Best regards Jacqueline Svensson
