Bad service

Good Day I made a full payment on my Game account with VVM attorneys in March 2021 ( the institute gave me a R2400 discount), I have received a paid up letter from the institution ( VVM) showing that I do not owe my account. The Game/ RCS account still shows that it’s active and that I owe them an amount of +- R2400 and it has been handed over to Norton Lambrianos Attorneys to my knowledge shows that someone from RCS did not do their job after I had made payment. I have contacted RCS several times requesting a paid up letter and all they do is send me from pillar to post. I was assisted by Abby Wyangard from RCS to a point where he advised that I should contact Norton Lambrianos Attorneys and started ignoring my emails. It has been a year and I still haven’t received my paid up letter, my name is listed on ITC. I don’t owe RCS anything, I paid my account in full! I just want my paid up letter and my name to be removed from ITC, it’s really affecting my credit score, I can’t even purchase anything because this account keeps on blocking me. I don’t owe RCS Game account. Please assist
