Dear SixtCustomerService

I was double charge too, I have booked BMW 520 AUTO in advance, the day I arrived Heathrow London , your employee said that I have to upgrade my car due to there was no car which match my booking available for me at that time, so I have to pay around 200 pounds more in order to upgrade my car from BMW 520 Auto to BMW 520 EST DI auto. However, I asked to pay the extra fees by using another credit card of mind. After I got back to my home town ( Thailand ), I found out that my card was double charge !!!!! ( one credit card at 813.42 pounds and 523.87 pounds) which means I was charged 523.87 pounds more.
