Poor service

I received an sms from one of the consultants at MBD that I must pay my standard bank credit card with the balance of R64 867.55 but made an arrangement to pay 700,I paid R700 last month then I received an sms saying my account was not paid as agreed.I called them to rectify that but was told I used the incorrect reference number and they are the ones who gave me the wrong account number.Now they cant reverse that amount to my account,I spoke to Sibonelo M one of the consultants she said I must email my id copy and proof of payment of which I did.Today I tried calling the call centre they just transfered me the was no answer at that desk,I want to finish to pay this account but this people are making it hard for me.Standard bank doesnt care they just tell you its under legal do they really check how are they handling thinks or they just to be busy collecting interest at our expense.
