worst after sales service

Ford Silver lake does not have the decency to respond to customers calls or emails purchased a ford firsta 1.4 2017 model, at the time the mileage was at 31000 took the car in for service at 37866 and told the disc are gone how does this happen unless the car was sold with damaged /gone disc...i don't believe Ford Silverlakes doing the checks as they state they are, I am very disappointed and will not recommend Ford Silverlakes to anyone. The Sales and after sales managers to superior to return calls including the HR manager....way superior to respond to customer complaints
