absa credit card

I paid my credit card in 2012 which I had believed to be a settlement of the account. Absa credit card div never informed me that I had a balance of R214 on the account. absa ran charges on my account from 2012 until 2018 without giving me even a single call. in july 2018 I got a call from attorneys that I have been handed over to them for non payment. upon following up with Claudette lewis from absa she informed me that the debt has been prescribed and I should not pay even the 949 balance and that she will get a paid up letter for me. nothing came from absa and I learnt today that absa blacklisted me in may 2018 already. please sort out this mess immediately
