Horrible service

I have a GWM PSERIES long wheelbase, which I service with GWM RACEVIEW, I have had this bakkie towed in more than 5 times with the clutch problem, everytime the bakkie is towed inn they keep the bakkie for 3 to 4 days and hand it back to me and it's able to drive for only 4 weeks same problem again, yesterday on the 24th May 2022 my bakkie went for service dropped it off at 8H30 I went to the dealership at 13H30 the bakkie was parked nothing done to it I went away came back at 15H30 bakkie still nothing being done at 16H25 I was told the bakkie will be ready, told them don't even wash the bakkie give it to me the same way, I left today the bakkie has no clutch again. So I decided to call a friend whose a qualified mechanic to check what's going on with this bakkie he went underneath and told me the clutch reservoir for a clutch master cylinder, only one look he picked up the problem yet GWM TECHNICIANS could fix the problem more than 5 times, now I'm stuck again. These technician don't seem to know what is going on with this bakkie.
