I'm afraid I have lost all patience with Avis, who apparently do not care that they have charged me twice for the same rental in Houston. I pointed this out to Avis UK, which is where I rented the car on my Avis account. The UK customer support were sympathic, and agreed that the second charge of around $380 was an error, but advised that they had to pass the matter to Avis USA for them to conclude. After a great many emails to the USA team, and also to the UK support team, all i get is an automated response with a support reference number. No other responses, and we're now coming up to month 3 since the illegal charge and since i raised the issue with Avis. How can they possibly think that this is acceptable? Like other reviewers, I must vote with my feet, and advise other renters to do the same.
