Renault review: no service and my vehicle is now in a poor state after service

At Seamans Renault George after my regular yearly service, my renault stepway traction control unit stayed on, the radio screen is glitching, sounds like a diesel engine (it's a petrol car) and the horn doesn't work when the lights are turned on. I took it back they reset the computer box and only the traction control returns to normal they said they will phone me when I can bring in the car to check of the rest of the stuff. It was the beginning of December. I phoned today one and a half month later not hearing from them, they said they will phone me back because a jobcard is logged but with no info. They did not even phone back.
