Listed Wrongfully On Credit Bureau As Arrear Client

I app**** for a personal loan through Ubank last year Nov 2020. The loan was paid out, but then a couple of months down the line the problems started. Firstly they deducted double from my bank account earlier this year whereby I managed to get my additional installment paid back to me, but then a month later they never debited whereby I made a manual payment via Eft to them. Not even one month I've been in arrears, but they've reported me on the credit bureaus that I'm x1 month in arrears. After reporting this matter when realized, it was fixed, but not entirely, because there was just a new profile created on the credit bureaus that indicated one profile is in arrears with x1 installment and the other is up to date, how is this possible if I only had one loan with them. The loan was paid up last month (Oct 2021) but still it shows I'm having an active balance on the first profile I had with them, which is not correct, and to top it all off, it shows x1 installment in arrears. Really guys, I've read through the previous comments clients have made on this website, and it's almost the same as mine, no man shame on you it's disgraceful and unprofessional of you to do this same thing to various people. Really if your systems are so pathetic or the individuals working for you, rather decide to close down, because this can't continue. I'm allowing you 48 hours to rectify this matter from my name and expect a paid up letter with immediate effect, and also my credit profile to be rectified. You have honestly disappointed me tremendously and I would never ever make use of your services again. You even caused me too not qualify for a home loan due to this absurd nonsense you've listed against my name. This is a friendly warning that I'm stating again that I'll allow you 48 hours to resolve this issue, if not I will take legal action.
