ABSA doesnt know how to close an account

Have had non stop issues with ABSA. I closed all my accounts and settled all fees on my account in March 2022 as i have immigrated. I am not getting several messages and calls around making payment for my credit card which i settled in March as per the agreement which was the fees. I have logged several calls and complaints to get this resolved, and i have emailed proof of payment for the amount to be allocated and still i am getting harassed for something that should be closed. I am not getting demands from attorneys to settle and fees for the lawyers because ABSA fails to resolve the issue even though i have submitted proof. As i am living outside the country and i have stated this several times, i keep being advise to go into the branch. I am not having to fork out a small fortune to fly to South Africa to resolve this. Very unacceptable service
