Arrears query

African bank ruined my credit record, in July I was told that my credit card is in arrears with R94,28 , on the 15th of July I called and queried that because a debit order went off for the instalment of June, an agent told me that he doesn’t understand why I’m in arrears because they received a payment. He promised to log a query and get back to me within 48hrs, we are now in august and I’m still waiting for feedback . On the 28th of July they debited the initial instalment and the “ arrears amount of R94,28” . Today I received my statement again it’s showing an amount of R252,75 in arrears, I called and an agent said she doesn’t understand where the amount is coming from because a payment was received.
