AVIS-Budget ********** Debit Order

I sent the following email correspondence to Avis regarding my vehicle booking that i made on the 27.08.2021 for 3days, through Holiday autos, one of their agents/partners, and now i am being charged things which i did not agree to nor authorize, as my booking with their agent, was "All costs inclusive" except for Fuel and Tollgates. See below email i sent to them, which they are procrastinating in resolving my dispute.

"Good morning Abraham, I would like to kindly request you to reverse the *******/Unauthorized payment of R3,829.83 which you debited my business account on the 04.09.2021, as I did not authorize Avis-Budget to do so. Its either you reverse it from your side, as I am also about to instruct my banker to reverse it. I am also going to instruct my lawyers to assist should you fail to reverse all these ********** transactions! I have previously told you that I booked the vehicle through Holiday Autos (i.e. as I have done so in the past, without any issues), and I paid in FULL! (i.e. Pre-Payment of R5859.65, which was done on 21 December 2020 as you can see on 2’nd page of Exhibit 1 herewith attached) And all that I had to do, was to go to the airport, and collect the vehicle, as I did on the 27.08.2021. To which your company held back a total of R10,000.00 from my Debit card and R2,499.75 (i.e. See Ex. 2 herewith attached) from my credit card equalling R12,499.75, which was meant to be refunded to myself! I see now there’s also a discrepancy between what you show as a Pre-payment on Exhibit 3 compared to what I paid to Holiday Autos, one of your third party merchants. On Ex. 3 herewith attached, you are claiming I made a Pre-payment of R4892.12 and not R5859.65 that I paid to your merchant Holiday Autos, furthermore, your merchant also said the invoice was VAT inclusive, and now you charged me an additional VAT of R1104.65, why is that so? I have previously requested you to explain the R1508.19 “Fees and Surcharges which you levied me, and I still have not received feedback from you. And according to your invoice on Ex. 3, the balance due quoted was R3571.83, yet you debited my business account R3829.83, why are there so many discrepancies, these actions or inactions by your company Avis-Budget are ********* and tantamount to **********"
