They dont want to assit the costomer

Absa send the updates to the credit bureau for the credit card that I own twice, One update's was done using the account number and the other one was the card number, and the instalment amount was the same with the balance of the credit card.I did visit the bank in sandton and there was no help they referred me to the collection department they can help me either, my biggest problem is than the credit card with R20000 limit is reflecting R25000.00 instalment in the credit bureau
