Wesbank account not closed

Basically, I had a car financed by Wesbank which was involved in an accident and was written off. However, the insurance did not settle the account. So I continued as normal paying the Wesbank account through a debit order however Wesbank handed over the account to PM&Hammond debt collectors. Please note that it is Wesbank process to hand over such accounts not because I was unable to pay them. The account then moved from Wesbank to PM&Hammond debt collectors and made payments regularly until I settled the account with a bulk payment in May 2019. I received the settlement letter from the Attorneys and from Wesbank.

on the 13/09/2019 I inquired from Wesbank as to why my account is still showing, I was told that the person who was helping me to close the account after settlement in May 2019 did not close it properly however the one that was assisting me indicated to have it closed properly.

However, on the 17/09/2019 I received another call from some attorneys asking me to make a settlement arrangement of R95 000. The account fully settle and having proof of settlement is still handed over. This has damaged my credit record.
