Won’t be using Avis again

I have been waiting since 26/1/25 for my deposit to be returned. It is now 14/3/25 46 days. When I tried to call customer care I lost connection and then kept getting “number does not exist” messages. I then called the branch and they said they had released the funds. I have waited 2 weeks since then as I was told it would take up to 9 days. And if no luck to go in to the branch. I have contacted the band and have been told the the release has not yet been authorized. So today I went to a branch and again was told there is nothing they can do, I need to send an email to customer service. I have now done that but await a response. All of this on top of 1.5h eating in cue to collect the cal. No communication about what was needed when collecting the car. Lack of ability to take to to pay/Apple Pay and the rude staff. All in all a very unpleasant first car rental experience.
