Answers regarding my Inquiries

I Andries Macsherry Du Preez, ID No. *** made contact with RCS earlier today regarding my Jet Account. I spoke to a lady called Thubisa and according to her my account was not with them anymore and she needed to send a email to her supervisor to retrieve the contact information for the Company that is now handling my account. She then returned with only the contact details for the company but not the companies name. According to her it does not reflect on the system. I then contacted the company and spoke to Katerina and according to her RCS to back my account on the 27th October 2020. I called RCS again and spoke to Thubisa again and I was transferred to Melissa. I asked why does it show on the credit record that an amount of R4359 is still outstanding when according to Jet it was written off and the account is settle in full. I require that this be investigated and sorted out asap. This problem has been ongoing now for months already and no one is giving me proper answers or solving the problem. I'm tired of excuses and my good name as a loyal payer is being dragged through the mud. I have all the proof of all payments. There is money due to me that was over payed on the Jet account of R140 which has still not been paid back to me and its now going on 3weeks already. Please respond as a matter of urgency or further steps will be taken. The companies name us Shapiro Shaik Defries and Associates.
