Capitec Bank is not simple

I took out a loan with Capitec 7 years ago while starting working. I couldn't pay my loan and Capitec handed me over, once i was ready to pay i contacted the where my account was handed over and i settled the balance in February 2023. I never closed my account i continued banking with them. In this week I app**** for credit and they advised that i was handed over i should sent them the settlement letter, i did that i emailed it to them and the lady told me they cant remove my status as my account was sold. My problem is I settled this account 4 years ago, I'm currently banking with them and yet they cant lift my status of years ago to active, i cant benefit from their products but they can benefit from me using their bank account. This is totally unfair in all angles, this account is not even listed on credit bureau, the consultant at the bank told me straight i cant get a loan with them but i can go else where, how do you tell your clients to go to another bank instead trying to keep me, Capitec banks slogan doesnt align with what they are doing at all
