Why is my account in arrears when it's paid up?

Hi There<br> I was a satisfied client until the Feb 2016. I posted a complaint a few weeks ago and Richard assisted me and resolved the issue for me. I was assured by Richard that the accounts were closed. He even sent me a paid up letter. Now I am still receiving sms's from Capitec threatening to have me listed as a bad payer. I took out 2 loans in Jan 2012 and they were both to be paid up in Feb 2016. After receiving those sms's I called the call centre and was told by Nosipho that I am still in arrears and needed to correct this by paying. I paid my loans back in full. Why am I still getting communication from you? I do not owe Capitec anything. The 2 loans were taken at the same time and were paid by debit order monthly on the same day. I never missed a payment and this too was confirmed, but my question is - why am I receiving threatening sms's? Please resolve this as soon as possible. I don't owe you guys anything. I also do not want my name listed on anything. I have been a good customer, paying my bills on time.<br> <br> Regards
