I hire a lots of cars in my travels around the world and this has to be the worse ever .. London Sheraton Hotel Branch , Be careful of this unprofessional Hire company ,Booking was easy on line from New Zealand , Used credit card on line to pay in advance for Rental , Problem started when arrived to collect car in London , Doing the paper work to After completing their PAYMENT AUTHORISATION CREDIT / DEBIT CARD for the additional (if any ) charges .. I then hand over my credit card (as per there on line Contract/instructions the same credit card they have already take the rental payment from , he now says the credit card now needs a pin number so the $1250 refundable Deposite for insurance to cover if any damage to car. I told him it is a CREDIT CARD ONLY and has never had a pin number on it ..He then called me a liar and says then that he can not release the rental car to me ..Called credit card company from there office and handed phone to him and the credit card company confirmed to him that there is no pin number allocated to my card .He then lied and said all car rental company's in UK do this .. So in short the F****** did refund my rental after having to email a request ,but still charged me for 3 days rental as they said i cancelled the contract and failed to show up to collect car. I then went to Euro car in terminal 2 of airport and then 20 minutes later walked out to pick my rental car ,, using the same credit card without a pin number. i Believe that was a scam from your company to force me into paying the non refundable FULL COVER INSURANCE OF GBP 266 which they would have taken payment for with my credit card (without pin number )and if i did you would not need the GBP12500 deposit same card but need pin number .. as such i am going to seek legal advice on this matter and am asking credit card company to seek a charge back for the 3 day hire charges . BE VERY CAREFUL OF THIS SHODDY COMPANY .IT APPEARS THEY MAKE MORE MONEY OUT OF CONNING PEOPLE FOR EXTRAS THAN THEY DO FOR HIRING A CAR ..
