STD Bank Making money with wrong information

I was at home in the afternoon in 2013, I received a call from a std bank. The person said I am one of the chosen STD Bank valued customers to get personal card of R33500 with no charges and I agreed. I collected the card at Sandton Branch after receiving a message that I must collect. I did not sign any document as the person who phoned me indicated that our call is recorded. The card was written credit card but I was told that is a personal card no one explain anything to me. After realizing that there are charges and are too high I consulted Std Bank. I was then referred to card division, that is where I realized that is a credit card not personal card. I then reported my problem to Std Bank complaint department, where they have referred me to their resolution department, my recording was retrieved the response was that they will reverse charges for 3 months. I then took my complain to the Ombudsman where the referred me back to standard bank indicated that it has to be resolved internally. I need help for the charges to be reversed and that the card should be personal card with no charges as stated by STD bank official not credit card.
