Bad experience with Wesbank.

I'm having a nightmare with my Wesbank contract. I had a used vehicle financed and after a year realised there was a policy added to the contract although it never authorised it and never received any policy documents. The purchase amount was R189k, a deposit of R23k paid, but according to the contract the financed amount was R203k iso R166k, which I then queried. I witheld a few payments seeing that I never received any response to my queries. While I was waiting for feedback, the account was handed over for collection. The total contract balance is R268 830 of which I've paid R268 741 till 10/2020 which is the contract expiry date. According to the latest statement, there is still R31k due? Over lockdown alone, R5373 in costs was added. I even went to their physical address reflecting on their website only to be told that they've relocated. Why is there no option on their website for customers to comment/post their bad experiences with this lot?
