*****ing accounts

I Received a statement to pay my edgars account i settled the balance in full R1022.70 as per my statement on the 30th September 2020 . I also sent a letter to confirm the closure with all supporting documents Today is the 06/10/2020 and no response has been received furthermore I know owe R15 more ,for what ,the call centre agents are of no help I have been calling them since last week and I hold on for 35 minutes for them to speak to a manager There also started charging interest on 6 month interest free accounts why and who authorised this i was a customer of Edgars not RCS I never signed up for any additional services The NCR needs to look into this as I do not know how someone can add all these charges and just do what they feel with the account . How do you pay a different amount than the one from the statement confirming what you owe ,This is a 6 months interest free clothing account not a loan . Card number ***
