Poor service from Westvaal Isuzu Menlyn.

We took a vehicle for a 45 000km service, indicated we had an issue with an Isuzu part fitted. It was fixed with double sided tape, and while still at the dealership, the part started messing about again. At the 60 000km service, same issue was brought to their attention, the service adviser told us that he will lodge a warranty claim. It has been more than a month now, and still no feedback whatsoever. Absolutely disgusting service from Westvaal Isuzu Menlyn.
