Double charged and taking forever to reverse

Yoh such nonsense. These people are disrespectful. When I picked up the car at the Isando branch. I payed the required amount and I returned the car. The invoice takes forever to come back firstly and when it comes back it doesn’t show the amount that needs to return from the deposit instead it shows all the charges and they will deduct that amount from your card as if you didn’t pay when you were pickup. They took 10 599.77 out of my account on top of the almost 13000 I paid in the day of pick up. I’m in so much distress and financial strain because of them and I already still have to deal with the trauma of my car accident. They are also taking their sweet time when it comes to paying money back which they say can take up to 30 days😱. I’m just in so much disbelief. When will this end? I’m going to take them to Ombudsman, they are causing so much stress. They don’t even deserve a star.
