AMS in Trowbridge

Worst place I have ever come across. I was told my car doesn't have an ecu. It's a 55 plate, I was also advised my head gasket had gone. When taken to another garage I was told I only needed a £3 hose replacing. Not only that he had my car for 10 days before returning it. It came back with scratches to the body work and a cracked back light. When complaining to the owner, he told me to F off and if I valued my legs I'd take the car leave and shut my mouth.
