Credit card nightmare!

I have an issue with my credit card, upon using the card for years with the same pin code when I wanted to use the card it declined saying that I had entered a wrong pin was sent a message for a number to be called to have the issue rectify, however when making payments on the card using the very same pin the card takes the payment,.customer care sent me to the store saying they could not pick up why I was not able to use the card as on their side it shows nothing, went to the store and they called Financial services who was also not able to assist upon several visits to the store they decide to send me Absa bank thrice to have pin reset, still the card had the same issue even after resetting it, advised them they need to send me a new card, card arrives within 2 days great, card has no pin provided so I took it upon myself to assume that I will need to use my old card pin bouy was I wrong when I tried using the card it said incorrect pin sent me a number to call to reset pin automated system could not verify my contact number call dropped. I have been a headless chicken trying to have this issue sorted out to no avail not to mention the amount of petrol, airtime and time I have invested in sorting out this issue but no luck. Someone needs to do something now because am frustrated and I have run out of options.
