Cannot get feedback from Geberit

We visited Geberit in Cape Town last week regarding a clients broken flush system. The receptionist advised that someone from Geberit would contact us to arrange a site visit. To date we have had no feedback from Cape Town branch. I have tried calling the branch numerous times today, but the phone goes unanswered. I called customer care in JHB and was put on hold for an indefinite period. When I called back, I asked to speak to the MD, but he was not in the office. I asked that some one call me. It has now been more than an hour and no contact. Why should we recommend Geberit products if they cannot provide a service?
