Payment was made, please clear this and update your system

Who is concept recoveries? I have a credit card with African bank, I owe African Bank, I made a payment of R300.00 to African Bank account on 1st of September 2018. I then receive sms saying This is a friendly reminder to pay Concept Recoveries, When African Bank called me to make arrangement, the agent said they don’t know who is concept recoveries and that I must make payment into the account I have being paying into all these months. If concept recoveries is collecting money for African Bank and the payment was made into African Bank account what is the problem? Why African Bank not notify concept recoveries that I have made a payment so they can update they side. This is a total inconvience, Plus Concept recoveries sending threatening messages that the taking me to court. But no problem, I will closed this account soon, and never will I take anything from African Bank again. Please speak to you Debt Collectors that’s doing work on behalf of African Bank, that I have made Payment into African Banks account and they must update my payment.
