Deposit Refund - Poor Service

I am extremely disappointed with Avis service. I returned the car on the 29th July, now they are giving me a run around just to get my deposit refund. On 01st August i called them and confirmed that the refund was processed and i should get it within 7 days, only for me to follow up on the 07th August and to my surprise it was never processed. Their customer care is not really helping as each consultant keeps telling me different story, except one named Thabang who tried to assist and called me back few times also. Today(13/08/2024) i was told i still have to wait seven days for my refund which at this stage i am not sure if it was processed. In addition i have also been trying to get details of the charges from the branch(Grand Central) but they have not even bothered to reply. and they are the ones who started this mess when they closed off the booking.
