Renaults nasty service

I am absolutely disgusted in the service and after care service of Renault Vredenburg. My wife took my Sandero Stepway in for a service and what we got back is a car with major airflow problems, brakes that is spongy, engine light going on at random times, *****s missing from the bash plate that causes a hellava rattle and a loose gear leaver. This is after a service. ***!
