Unauthorized deduction from my credit card

<p>On 31 October 2016 an amount of R6819.50 was deducted from my credit card by Avis Rent a Car Johannesburg ZA ********** ********** ********** 38. On 1 November 2016 I sent an email to Avis, I got an automatc response back that Avis will follow up[Case: vnooeY, Reference: FvJfFG]. No response form Avis to date. Then on 4 November 2016 I made a call to Avis Customer Care, the lady I spoke to said they will look into it. Until now, no feedback from Avis. On 7 November 2016 I sent another email and received another automatic response [Case: R5cIzD, ***]. Until now, no feedback from Avis. On 10 November 2016 I called the customer service centre again. I explained to the lady all the times I contacted Avis and what my query is. I held the line for 10 minutes while she went to follow up. The response from Avis was that they cannot see any money reserved against any of my rentals. They said they also contacted my bank and that there is no transaction pending from them on my credit. I had to explain to her that the amount was never pending, it was directly deducted from my credit card. The Avis Customer Care e-mail is useless, I am still waiting for any response and I am still waiting for my money to be paid back.</p>
