Unable to close Edgars account

I have been trying unsuccessfully to close my Edgars account since end September 2020. When calling RCS, I was told that my account hasn’t been transferred from Edcon. When calling Edcon, an automated message informs me that I must call RCS. I have been to a branch several times to assist me, but it’s the same pingpong game. I also sent numerous mails to both RCS and Edcon. The automatic reply emails promise that I will get a response within 48 hours- it’s been months. I’m sure my nil balance has been added to with fees by now. So frustrating.
