Bad bad unprofessional service at tygervalley Renault service centre

If there was zero for this review I would give it to TYGERVALLEY RENAULT ..I booked for my car major service a month before the date and I was given the quote so i knew what will be done and they knew also.arriving at their workshop on the date GERART did not prepare paperwork and I had to show them confirmation SMS that I am supposed to be there .left the car and fetched the car at 17:00 only to find out they only did minor service ...campbelt not replaced and I was not told this during the day.my car is still is showing warning sign on the dashboard that it's not serviced because they did not tick it off on the system ...apparently the system is offline.i was ****ed off which I still am because they were not professional enough to tell me what is happening,I wasted my full day for nothing for a car that was booked.what is the point of making a booking then?they told me that I need to bring the car back and they will do all without doing any booking(really!!).why not call the client during the day or prior the day and explain the issue!!yeeeerrrrrrrr
