settled account and still being billed!

I came back to Queenspark Kolonade (10September15) to pay total settlement amount balance to close it off. I was assisted by Gloria, she called RSC asking for the settlement amount, they gave her the amount of R4745.75. My brother swiped his card and told them, he doesn't want me to use the account anymore, they must verify the outstanding total settlement amount balance and he will pay it all. The sales ladies are my witnesses that I settled my account and I have receipts as evidence.<br> <br> Later on I'm harassed by the Queenspark ,bombarding me with an sms that I must still pay R200.00 on my closed account, the same day I speedily drove back to Queenspark Kolonade store, they called RSC.RSC sent a feedback that I still owe R1200.00 for an item I purchased on the 07September15.Gloria again called RSC ,requesting the person who assisted her with settling my total settlement amount, told them I already settled my account and I owing nothing, they said they will investigate the matter.<br> <br> <br> Queenspark Kolonade personnel told me any purchase from them reflects on the RSC system after 48 hours, I came on the 10September15 to pay up my total settlement amount account ,after 48hours was over.
