Unhappy Customer

I bought a car a 2014 Mercedes Benz A250 AMG from we buy cars Silverlakes on 26 November 2021 it was under warranty and it has motor plans cover from We buy cars and outsurance.on 5 January 2022 the car just stopped on the highway I contacted WBC and they fetched the car and took it to Mercedes Benz Rustenburg. WBC then said Mercedes workshop is expensive they towed the car to some workshop in centurion even today the car is still there.I am paying for a car which I don't have since January I tried to cancel the contract with them, they refused to give a paid-up latter which I must give to the bank. They requested me to pay R12000 for the kilometers I drove I payed even today they don't say anything. If you wish to contact me Paul ***
