Chery needs an upgrade with service delivery

took my vehicle for service, with in a week i had an issue with the brakes. i was requested to bring the undrivable vehicle 30kms to service provider. this was not even my fault, as there mechanic gave a written report that there was enough life on the brake pads. i had to pay the cost for the repairs. a week ago the service light came on, both chery sa and the umhlanga chery has not responded. why do we take service plans, when we are paying for a useless service and we need to pay again.
