Avis Car Rental - Believe me you will never get your deposit back without a fight -1 month, still not received!

Had such a bad experience with Avis!!! Was in a car accident and got a rental through my insurance, firstly the lady that helped me the first time was friendly up until she notice my license has expired, fair enough I do get that, but to be rude just after that??? Not sure if it is customer service really? Then I got licensed sorted went back got the car, brought back the car when my time was up using it, in perfect condition and the petrol tank was full like they asked. A friendly guy told me my deposit will be paid out in the next 5 working days. Still waiting.... 7days after I contacted them regarding my deposit, I spoke with Lizel Ward, she was helpful and frindly and said she will e-mail my bank and find out if the aurth was still pending and will revert back to me. Got the mail so I left it for a few days, phones Lizel back asked her about my deposit not being pais out yet, and man was she rude, she told me i should phone my bank myself and find out because she did everything she could and that it is not her responsibility to make sure the money is in my bank. I kept my cool, ask her why she is being rude, because I was not and you can't resolve a complaint being rude like that. (they more than welcome to listen our telephone conversation since its being recorded) Lizel said she gets people phoning in being rude to her about deposit's the whole day already and that it is not her responsibility to check with customers bank where the money is! I mentioned again that I am not rude to her I was nice all the way and I would just like to know what the steps forward is regarding my money. She went on! I asked to speak to a manager, witch she rep**** they only have an supervisor and not a manager during covid ( Please note this is level 1 we are on) she eventually gave in and asked that I should hold.. waited about 2min to speak to the supervisor but no it was Lizel again, this time apologizing so much,, because she went to go have a look at my account and notice her wording to the bank was wrong. She just asked if my deposit was still on hold and not top release it..... she would have contacted me when my bank responds after she re-sent a mail to get the funds released and I still have no answer what so ever regarding my deposit back??? It's a month now, if you phone customer care, nobody can assist, because nobody is in office. I also said to her that I am in the customer service industry as well and if I had to speak to one of my customers like that, I would get fired on the spot. But here I am almost a full month later yet no deposit back from this company Avis. Please think twice before using them, looks like being nice to them does not help at all and how things are going, I might never see my money again! I asked my insurance to move me to a different company for car hire, because I will never recommend nor use them ever in my life again! Do not even think they will reply to this...
