Bosch silverlakes

I am highly disappointed with the service I have received from Bosch silverlakes. My Isuzu 4x4 is standing there now for almost 4 weeks to sort out a 4x4 and some wiring issue's. On Wednesday 23 February 2022 I have received a call from them telling me I can go to collect my vehicle the problem is sortet out, just to find out that nothing has been done to the vehicle and they charged me over R 3000.00. I have ask them to have a look at the 4wd, ABS light that was on and the system not working.

After inspecting and testing the 4wd system and work they have done I realize the problem is still the same the 4wd still not working ABS light is not even showing on the cluster if the key is turned on and the engine wiring harness is not even taped up and closed properly (looks like the work has been done by a back yard mechanic) I also reliced the globe of the ABS and check 4wd lights was removed from the cluster so that it looks like the problem was solved.
