Unprofessional business

I had a loan that was handed over to MBD, so they have been calling me and in communication with payments, on the 5th of September I called asking for settlement fee I was told, then waited for the email that took long I ended up paying and received the email 2days after settlement payment. And the settlement payment saying R35000 and I had paid R380000..... Then I kept calling and sending emails with no success even now, the call center people can't even access the system to check what's the status or customer care keep saying they will get back to me and now it's October DirectAxis is saying I'm still owing them,,.,!!!! MBD is really failing me.... I'm left with no choice but to had them over to my lawyer's because now they'll interests added for the new month of which I finished paying everything on the 6th of September 2021...im greatly disappointed
