Avis Delayed Updating their Records and Double-Charged Me

I rented a car from Avis Port Elizabeth International Airport on 3 Feb 2023 around 18:50 and returned it on 4 Feb 2023 between 18:00 and 18:30. That is for ONE day.

When I returned the vehicle and the gentleman that assisted me took the key, I asked if I needed to sign anything and was assured that I did NOT need to sign anything and that all was well.

On 7 Feb 2023, I get an invoice saying I returned the vehicle on Sunday 5 Feb around 7:36am and the invoice reflected 2 days worth of rental! It seems when I returned the vehicle, they forgot to update it as received and only did so the following day, hence the double charge.

I sent an email to *** and *** on 7 Feb 2023. Sent a follow up email on 9 Feb and got a response notifying me that an extra day dispute was lodged with the branch and that feedback would be provided. I even asked then to check their CCTV footage to prove that I returned the vehicle on 4 Feb.

Sent a follow up email on 11 Feb 2023. No response.

I even called the branch 8 Feb at 7:54am and was told that the branch manager would call me back later in the day. No call.

Called again on 9 Feb at 7:12am and again promised to be called back later in the day. No call.

Called again on 11 Feb 2023. No success.

Dear Avis, is this how revenue is maximized by charging delaying to register vehicles so that you can charge for extra days? This is really sad. Your auditors must look into this practice.

Could you please refund me. Please.
