Avoid east rand opel/isuzu

They were paid a week in advance for repairs that was needed on my chev sonic rs turbo, they received the parts a week later and repaired the vehicle and it was tested and tested by them before i picked it up a week later. A couple of days after the car started the same problem again, i took it in they reset codes and the same problem started on monday, when i contacted them and asked for a qoutte on the second thermostat. Its now thursday and like 10 calls and waiting , no qoutte still, when i phone in everyone is busy or i get transfered all over. Bad, unprofesional service, no more company vehicles from isuzu willrather use key in natal
