Very poor and credit report hindering

On Friday 13 April I settled DMC account number ********** 9 and ********** 8, but 4 days later account number ********** 9 was remove from my credit record and I called DMC to enquire about account number ********** 8. But the lady called Khethiwe(25-04-18 09:01) told me to call later as she will contact credit bureau and I must call later. I called again on the same day at 15:27 and she told me I called earlier and hung up on me I called and she said i must contact credit bureau to dispute the matter. I asked her if our calls at recorded and she hung up again. I called again and she transferred me to Georgina and all I wanted was to confirm the Khethiwe's name and ask myself if transunion is helping consumers since Khethiwe said on the 16th of April and update was sent to credit bureaus.this effects South Africans but make an enquiry but credit bureau will update within 12 hours. DMC and credit bureaus shouldn't be baseline for affordability check. Apparently I am paying monthly installments of R15009
