Avis car hire the Fruad

I hired a car with Avis, East London Airport Branch on the 7th of October 2020 for 3days, I am yet to see my deposit refund. It's been 3 months and they have not made any attempts to give me an update. Each time I call requesting for an update, I am met with hostility and unprofessionalism. Am at the ends of my wits with this company. The way I see it they want to de***** us (cause am not the only one, there are other cases similar to mine, I am told by said employees) because they were on the verge of closing down their business due to the lockdown restrictions, as a result they have closed down one branch here in Vincent. Unfortunately I would not recommend this business to anyone, clearly Avis doesn't value their customers, surely returning ones deposit shouldn't take this long? Or are they hoping we'd die of covid and they, in return would gain and invest all that they have ****med from their customers of? Could this be your business recovery plan Avis? To **** the very same people who have supported you over the years?

Consider this my last attempt at getting my money back, after this I will file a case in the small claims court.
