Edgars needs an Accountant to contact me ASAP

I am at my wits end with endless phone calls made to Edgars customer care and to your *****/Disputes department. After my 3 disputes have been reversed, my installment was never recalculated. After many calls and emails, I received confirmation that my new installment was R147.19. I paid R200 on my account on the 24th of July. I am having endless ***** on my account and being charged for a "late charge". What is going on? Now I have another transaction on my account from Mall of the South ?? Its Not my purchase. I handed in my dispute on the 14th of August and when I phone, it has still not been received an resolved even though the store admin manager (Retail Park, East London) said it would be. My account balance after payment made on the 24th of July 2020 must be R683.19 less the "new card fee" that has been reversed= R633.19. I have proof on email that my account is up to date! Not one cent more. Who can sort this out ASAP? I have settled this account in full and they are still sending me statements with ********** and incorrect transactions on and harassing me with calls and sms's. I have made so many phone calls and written so many emails and no one is resolving this issue.
