PATHETIC SERVICE

I have RCS contempo account, I managed to pay the balance that I was owing on the 15th of December 2020. since then I have been receiving messages and emails that my account has been handed over and am in arrears. I have called RCS plenty of times with no success until I called once again on the 18/03/2021 at 12:07pm where I was assisted by a lady called CHRISTELENE, she apologized and said her superiors saw that there was a mistake and I was charged twice so they are rectifying the mistake and they will give me a call. I haven't received a call from RCS even today regarding this matter and on the other side they keep on sending those annoying messages that I am owing. I will not pay for something that I am not owing, even then arrears accrued on that account I will not be liable for. if I end up having a bad credit record because of this then there will be consequences to face. RCS staff should do their work and rectify their mistakes, I am frustrated its enough.
