Unjust listing

I am making an additional attempt to resolve a query that has not been attended to. I lodged a complaint for an undue process that was followed on your end. I cancelled my membership in May '24, because financially it was no longer viable. I was advised that there was an amount outstanding which I needed to pay in. I had no challenge with this. The only issue was later on I received a call from one of your collections agencies and a barrage of SMSes referring to a Bankmed debt which I settled years ago. I immediately made contact directly to discovery and was advised that the debt was settled. After this there were no attempts made to settle the issue. Now I have a default on my name. This is incorrect and unjust because I have received no correspondence since May relating to this and no prior notification was sent to me regarding this account an as such the default should be removed.
