Unauthorized debit order by Nedbank

I had Go Banking credit card in 2006 and I couldn't pay it then the account was handed over in 2009. I registered with trans union in 2011 and being receiving my credit report yearly since 2011. The account was removed on my profile in 2012, since then I haven't been contacted by Nedbank.

Till in July 2019 when they decided to debit my account with three transactions without contacting me. When I call the Nedbank they referred me to Jay Mothobi attorneys who handles the debt but when I call the attorneys they referred me to the bank as they claim not to transact any debit orders. I was sent from pillar to post just to get answers and explanation of theses transactions in one month.

I still don't understand why would the bank wait for so many years to action on outstanding debt. I was later informed by the attorneys that there's default judgement in place for this credit card which was done in 2010 and not listed on my credit profile.

According to me the debt was written off and removed from my profile why would the bank decide to deduct three installment in one month.
