Took our car in for a service and a safety check. Car was running good before we took it in. After receiving the car back, directly after the service occurred, the car kept overheating. We topped up our EMTPY coolant tank (which was full before) and now days later the car overheats every 5 minutes. Called up and asked what they had done considering it had never done this before to be told it wasn't their mistake and they weren't taking responsibility for it. Absolutely horrible experience and we will never be doing business with this company again.
