Customer service

If I could I would give 0 stars. I have a loan with capitec, get paid on the same day every month, which is the 30th, they tried to take the money early this month (December), I still haven't gotten paid. Phoned, the lady fixed it, went onto my app just to see that my credit score has been affected by this, phoned again because, what the hell? The second lady was the rudest person I've ever talked to, from answering the phone, to not listening to my explanation to blaming ME for their error!! This is absolutely ridiculous! To be treated like a ***** that doesn't pay when i have NEVER MISSED 1 payment! I wish I could flag certain customer care personel, she is not good for the company and shouldn't be in customer care with that attitude, she wouldn't give me her name either knowing that she is being rude to a customer. I am seriously worried about my credit score and they just don't care that they made a mistake!
