Avis Can’t Account for Unknown Extra Deposit!

I have been using Avis for over ten years. However, my last Avis rental was HELL. Avis debited an amount of R19K from my credit card for deposit and monthly rental. Then, for reasons unknown to me, Avis credited my rental account with extra R6K. The combined amount was R25K. I have no idea where the extra R6K came from. The next month, Avis debited an amount of R13K for a month rental, which was agreed upon as per the rental. Avis tells me that, I owe them R6K. I did not receive the R6K. Nor was it deposited into my credit card. It was credited to the rental account and not my credit card. Avis, cannot account where the extra R6K comes from, as it did not come from me. Avis has refused to resolve this matter, but has been sending me SMSs and emails, reminding me that, I should pay them the R6K. Avis is so adamant, that, I owe them funds I did not receive. Avis is aware, that, they did receive the above R13K for the month’s rental, but Avis also wants the R6K added to the R19K to make it R25K, which R6K, I am not aware of its origin. As these were digital funds, Avis should be aware, where the extra R6K comes from. Avis should also be aware, that, the next R13K rental was paid in addition to the initial rental/deposit.

Be careful when renting a vehicle from Avis. There’s a possibility that, you will be threatened to pay digital funds (where no deficit is accounted) credited into your account without your knowledge. I’m done with AVIS. This has been a horrible experience. I am regretfulI and have had enough of this abuse and threats.
