Edgars Credit inflation and refuse to refund and to close the account

Credit amount was inflated during the merger with RCS. I owe thousands that I don't even know what they are for even though my last purchase at Edgars was prior to the COVID isolation period. They say I owe an amount I never owed them before. I phoned to ask what are the payments for, they say they are for services, when I checked the services I realised that when they moved my account they included phone insurances for phones that were lost and the replacement phones. I queried this they referred me to IUA. In July 2023 I asked them about the amount owed to close the account they said it was R2000, 00 of which I paid and requested my account to be closed. The following month they said I owe the same amount paid plus another R2200, the total amount owed was now R4200,and from then on every time I pay an amount the credit increase includes the amount I paid. I then realised that Edgars owes me but do not want to admit or close the account. I then wrote an email requesting reimbur*****t. I'm still not winning in closing the account.They want me to send an affidavit with pictures of my card back and front as well as a copy of my ID of which I don't understand what these are required for. Hello Peter I'm at dire straits.
