Pathetic Customer Service

It is with utter discuss that I am doing this review never have I thought that I would have to write a review like this. Customer service is supposed to be of utmost importance. Not what I experienced at "AVIS Cape Town International" So I arrived at 08:00 to get my vehicle stood in the line was assisted almost immediately. The lady who helped did her job well I wanted to pay with my wife's credit card and then she told me that the owner of the credit card should be the doing the payment that I fully understood 10/10 for them. Then I was told that I could pay cash so I asked my wife to transfer the money so that I could do the payment with my cheque card, due to the fact that left counter I was told that I had to go back into the line which went all the way outside this took me about 40 min to be helped. When I wanted to pay with my cheque card (cash) I was told that they had to check my card with the bank. This took them about 10 minutes, Then the lady comes back to me telling me they can't help me because of the team who checked the card said NO. Now I am starting to get frustrated when they tell me that I could go get cash from an ATM which is situated about a 15 min walk to and from them. I got the cash which I was not very comfortable with for safety reasons that are. This made me feel like a ********. You need to remember I have no clue to what your procedures are to payment methods. The fact my cheque card was not good enough for cash payment is beyond my understanding. This could have been dealt with so much better.
