Most Pathetic Bank

I have been an absa client for as long as I can remember, I have had so many issues I cannot even keep up anymore. I have considered moving my accounts to another bank as this incident was the final straw. I recently travelled abroad informing absa of my intentions, my card was given at the rental car company which they nicely processed payments on my account without my knowledge, even upon my return the rental company continued putting amounts through. I informed absa ***** of what was going on, I had my card stopped and I received a message to say that my card had been refunded. I continued using my card and paying in like I normally do, only to find that my card declined. I once again contacted ***** they couldnt help me as my card had been handed over for debt collection. I could not believe what I was hearing. I contacted debt collection only to find that the rental car company had banked the amount on the 13th April, the lady who tried to assist could not provide me with the proper information. I then tried calling ***** again but with no luck. I need answers and need them immediately I am still trying to understand what is going on.
