Emailed / Called more than 5 people - problem still not fixed 2 months later

I recently had my Blue Bean credit card upgraded to a Gold Card. When I asked what account I must now pay via email I was told I can use the Standard Bank card option instead of the Blue Bean beneficiary. The first payment was not picked up by them and I did not know it was not allocated so when I received my statement for the next month I saw a high monthly payment due. I paid again MORE than what was due to bring down my installments and again the payment was not picked up. I only realised after the 3rd statement I received that my payments were not allocated. I phoned and emailed MANY people trying to have this fixed which took a VERY long time. I asked that they allocate the payments to the months in which it was paid as to not affect my payment plan. THIS WAS NOT DONE. I am STILL waiting for a reply from my last email I sent but received a statement that was not allocated correctly. There are too many people not willing to fix a problem here, but rather pass the buck.
