Avis Service sucks

I rented a car from Avis King Shaka Branch on 30 March 2023 to 08 April 2023, paid well in advance for the rental as well. When i got the keys the car was not parked in the bay they advised, i had to go and look for the vehicle. I lodged a complain to the Avis customer care team on 13 April 2023, they acknowledged the claim and sent it to King Shaka branch on the day. Basically the cars wipers weren't working as expected, the alignment was out as the car was pulling to one side, the fuel gauge was faulty, i filled up the tank on the day of return took a picture that shows full at the Avis return depot, switched off and handed the keys to the staff member, when he turned on the ignition the bar dropped by 1 notch and Avis billed me for this. I have since supp**** the evidence as part of my mail but no response yet. Not to mention the speakers in the car was also crackling even when the radio is turned off. As an Avis preferred client i feel let down and will never rent from them again.
