Technostar auto body terrible serve

My car was booked in with Techno star ...the first time I went to see the car the paint work was not matching I had to go back again to fetch it the next day ...when I drove the car the alignment was off and the car was nt going straight and it's a new car with 25k on the clock i wasn't happy so I took the car for a dekra test ...I told the insurance and technostar all the issues I'm having and 2 weeks later they fetch my car promising me it will be ready the same day...they pick my car up in the morning and have it the whole day to tell me that no accessors came they sent my car back with nothing being done and said that the accessors will contact me
