Bad services and don't know what they doing

Worst service ever. Sent my car in for a service and said I had a gear box issue. Service was done and had to call these people so many times to find out about my car or what's happening and they would never call me back. Only to have my cars service light back on and now my cars worse off and no one can get back to me or call me today and getting no response. Never take your car there.
