Edgars Accounts Department and RCS Group - problem with my account

I have R2800 limit on my Edgars acc. In the past year I have paid back R3200 and according to Edgars my account is still outstanding with R2700. I have sent numerous emails wuthout receiving any reply , made call after call only to end up holding on for hours with no success. I have been Threatened by RCS Group that I will end up with serious credit score issues if I don't pay. I even visited Edgars Pavillion to see if they could assist me but thar was also a fruitless exercise. The call center promised to request statements for a year from Edgars accounts department which after two weeks still hasn't arrived. I am really beyond frustrated with the *********** staff that works at Edgars, RSC Group and the call centers Edgars make use of in particular Ignition group. I will definitely never refer anyone to Edgars to open an account there purely because of the tons and tons of unresolved problems I am having
