Technical Issue affected credit score

I have 2 loans running concurrently with Capitec. I'm 12 months away from paying off my 60months loan and can say that I am grateful that I have been able to keep up with my monthly installments ever since. I am certain that Capitec Bank has a salary trackers as the money is always deducted from my account by the time I wake up. I received an SMS days after pay day stating that they have not received my payment for the "big" loan yet the "small" loans was paid(from the same account I've been using from years). I called the Service Centre to enquire on this and was advised that they experience a delay in payment from FNB and STD Bank but it will be noted on my account that it was paid. Fast forward 03/12/2020 I received an SMS "thanking me" for my payment. I took it upon myself to check my credit score only to find that due to Capitec's technical glitch Dec have been flagged as a non-payment month(with makes it the 2nd incident with Capitec as the same occurred in January on this year. This is highly disappointing as I have worked really hard to maintain a good credit score and now this puts me in bad light. I also want them to use the same energy they use to send us "non payment" SMS's to notify us of their technical issues. I NEED them to clear/update that "non payment" flag as this was not something that I caused. This is rather disappointing and discouraging.

Very despondent client
