A delayed international train stopped me picking up a car at the train station till the next day. We phoned Carrentals and Alamo to warn, but Alamo insisted on a completely new booking once they realised that the booking was through Carrentals. Carrentals did respond via email to my complaints but insisted that the entire original multiday booking was forfeit. In fact their Terms and Conditions stated only that "Auto Europe does not refund any unused days if the customer does not show up, shows up over 2 hours late without contacting Auto Europe or returns the vehicle early. In case of a cancellation due to officially acknowledged Force Majeure Auto Europe will charge an administration fee of GBP 25 only." (Auto Europe is another name for Carrentals.) So I wouldn't get my money back for the unused day (fair enough) but should not have lost the rest of the booking. Carrentals would not budge and did not address my arguments. But the credit card company restored the full payment to me and Carrentals did not dispute. That is the way to solve it.
