Disappointing lack of feedback or attempt at service

I called the Kyalami branch spoke to Eduard more than a week ago requesting a quote for a major service on a Cadillac. We previously had the car with them and received exceptional service. Eduard kept saying he will call me back, but never did, I had to call continuously to get an update. He said the foreman is struggling to get parts. After one phone call to Williams Hunt in Fourways they able to get the parts and give me the quote. I feel that Eduard did not even try. It is very disappointing that from one sales adviser you get exceptional service and from another nothing. No attempt was even made on Eduard's side to call me and tell me they are still busy.
