Problems with double charging
While the car rental staff at the airport were wonderful with a quick check in and out, customer service regarding double billing for a rental has been much less satisfactory. While I prepaid for my rental and was thus charged, I was then charged for not picking up the car. I had picked out another car on their app when the one I had prepaid for was not available. I was easily given it at the airport. So I was shocked to find a second invoice. I talked to an agent on the phone for half an hour but he could only find one bill and had me email their service/help email. I have been waiting for a response for 10 days and have emailed twice and am now considering disputing the extra charge on my cc. It has been unduly stressful and although I am traveling a lot due to family illnesses I will not use SIXT again.
