Standard bank is a ****

Hi,In May 2017 I bought a vehicle and was financed by standard bank,I used the car for e-hailing services,it was a suzuki Ciaz 1.4 gl. The car was valued at R199,000+ and to date i paid over R300,00. Last year September was my last month to pay offf the car which i did and i stopped and went to the bank to enquire about the registration certificate,I was told that standard bank had an insurance cover on my behalf and i got quite confused because I don't remember taking a insurance cover with them,I was not alerted nor told about it on the statements it kept on appearing I even went to their lawyers and asked about it and they couldn't give me a clear answer and the lawyers just concluded by saying keep on paying the car and work,which I did,after the last payment I stopped all payments I mean I've paid more than R300k on that car. We'll seeing as they saw an opportunity to **** me like they do to people,they came the following month which was October to repossess the car,I was told that I'm in arrears of 90k,how when I've paid them so much,I gave thme the car and start communicating with them and till this day no one can explain to me how I got to that amount and what the need repossess the car after my last month paying it,mean why wait for arrears to get to 90k for them to make a move when I reached my last month? In the e-hailing business you need to have an insurance cover that includes passenger liability which I took with a company named lion of Africa, had my own private insurance.. I never took a cover with standard bank,standard bank is a **** no one can convince me otherwise till this day I'm still waiting for thme to get their stor straight or bring back my car.
