Update my credit record profile and close my account

My name is Lindiwe Nhlapho, I have an account with Edgars. on the 27th June 2018, I settled my debt and paid R3880 cash at the store in Wonderpark. I check my credit profile with Transunion and other credit bureaus companies almost on a weekly if not daily basis to see if my record score is improving. Long story short, today, I extracted the report, and news flash my record still shows a balance on the Edgars account, over 5 weeks after making a payment. I am so angry and disappointed, Edgars has lost a customer today. cancel my account, make sure my record is updated in the next 3 days, or else I am marching to the consumer rights commission. This is unacceptable. I want nothing to do with Edgars, they treat customers badly and contribute to the low credit scoring even when accounts are paid in full before the agreed time.
