Car Maintenance policies

i took a M Sure policy out because the vehicle i purchased from Top Speed Motors in Vereeniging which i paid cash for (R230 000) had no guarantee because i paid cash which i was only told after i took possession on the vehicle and established that there was something wrong with the gearbox and was told by Top Speed Motors "not their problem" so i took a M Sure Policy out but when it came to getting the bakkie gearbox fixed - Quote R58000 suddenly M Sure would only cover R8000 yes each car has a category but when i took the policy out that is not what i was told so i had to pay R50000 out my pocket so because of this i will be cancelling the policy and don't recommend them to anyone
