Incompetence and Extremely Poor Service

I have a Game account which was taken over by RCS. I settled my Cash Advance on 11 September 2018 with the amount which was given to me telephonically on the same day. I app**** for a bond on 3 November 2020 and this week I found out it was denied because RCS reported me to the Credit Bureau for being in arrears on my Game account for 90 days during December 2018, January and February 2019 and nothing after that which they never informed me of. According to them I “short paid” the settlement amount which is absolutely ridiculous! I had them on speakerphone and had a witness of the amount I was given which I wrote down and promptly paid. According to RCS/Game they record all their calls. If I was aware that I was in arrears of any kind this matter would’ve been sorted out by then. I still have the Proof of Payment. Now when my bond was denied I was so desperate I offered to pay the outstanding amount for those 90 days so that they can clear my name from the Credit Bureau and I was informed I cannot do it as my account is currently up to date and paid. What kind of ******* is this???? Also when I had an RCS Account I settled the account and closed it. They told me it would take 35 days. After 35 days, to my dismay, the account was still not closed. It took me SIX MONTHS of constant emails and phone calls which takes FOREVER to get through and then being transferred from pillar to post and getting cut just start all over again to finally get my account closed. I have never in my entire life dealt with such an *********** company in my life with such untrained staff and the worst service ever!
