Poor service at Bosch OE Service alrode

The phathetic service and trial and error method used to diagnose the vihacles.

Repair are done and have come backs . (1) vw Amorock : cambelt repairs break down was blamed on the cambelt. (Done twice n never got right and lastly dropped the valve) (2) Ford focus : fixed for overheating and break the engine hours after that taken from repairs. (3) Jeep Wrangler : engine rebuilt we never received old piston but paid 107000 for rebuilding the engine with includes 32000 for new pistons. Recently take it for changing of burnt wiring harness ,they alledge they can't get some harness we source it ourself now they can't get the car right .they took computer box and ECU for check up n then advised to check body control box . We don't know whats next on the trial error They don't want to accept that they cannot get the car right n how long will the car last after this repair.
