Avis

Avis is robbing people! Please people read your fine print before booking with Avis. They don't tell you up front about cancellation fees!
I booked with Avis and never got a confirmation email from them up to now. After checking the FAQ, they say if your booking needs to be processed for availability it will be placed on hold and you'll get an email in 72hrs and that payment will not be processed until the booking is confirmed. I'm still waiting for the email!
I tried cancelling the following day as I found a better deal with Enterprise. After trying all the customer service numbers and staying on hold with Avis for almost 2 hrs (complete waste of time, tactic to get customers to hang up by the way)...I decided to try again the next day. Called the next morning and got through after about an hour (customer service hotline sucks). I was told by the representative that since I cancelled in less than 48hrs there will be no fee. He sent me a cancellation email upon request. I was not worried as the payment at that point was not processed. I was so shocked to find out later that night that the money was taken. Of course, customer service is not answering as per usual. "high volume of calls they say"
Eventually got through the following morning and now I'm told there's a £40 cancellation fee! Even though they took the money after I cancelled because the booking was never confirmed by email. The level of unprofessional injustice! I am disappointed and embarrassed by Avis. Upset, feel robbed!
Will not recommend!

There was no handover with instructions on how to use the vehicle properly and safely. The 6-week old vehicle had tires with mismatched threads and therefore a very unsatisfactory situation. It took almost 15 minutes to contact Avis Car Hire at the airport to complain. I had to insist on a replacement car. I would not recommend Avis if this is the typical experience.
