Bad service and refuse to repair damages

Booked my Clio IV for service and suspension problem and noise in door. door noise still not fixed after the car was there 3 more times for suspension repair and told them again about it. i had to take the car back the next day to prove suspension fault to tech. Car was booked in 2 days later. 5pm phone me the car must go for a shock test the next day. what did they do the whole day?. Shocks ended up to be the problem and maintenance plan will only pay for the part not labour. verbal labour quote R882.19 approved. booked the car in 3 weeks later as they never phoned me parts are there as i had to smell it. car there for the day. phoned me 3pm i must bring it back another day they did not find time to work on it. when to see the workshop manager at 4pm. now they want to fix it. 5pm when to fetch it. clearly it only took them an hour. invoice R1499!!! what happened to the R882.19??? no-one phone me quote changed. still invoicing 2.2 hours for 1 hour work??? *******. Mags scratched. tech will not except it was him. clear damage from placing down wrong way. 4th renault in 10 years and will be the last. not even buying any brand they will service. these people make me sick...
