Tried to book a car online for my UK trip - entered all details, including credit card, and got a message to the effect 'something went wrong, try later'; I tried later - exactly the same outcome. So I booked with a different company (very straightforward). Few days later checked my credit card statement and Avis had charged me for 2 identical rentals - they took the money but I had no record - no email, no booking reference, etc. Tried to contact Avis but their "..systems were down..". So emailed their customer care (haha) people, again and again - all I get are automated replies. 3 weeks later and still nothing. I have reported these transactions to my bank as fraudulent (i.e. unauthorized). As I have no confidence in getting my money back I will find every review opportunity I can to encourage people to NEVER use this company EVER.
