Telephone permanently on Voicemail and NO replies

I had to drive 150km to Emfuleni to change contact details on our company properties in Vanderbijlpark to be pushed around from one person to the next, eventually I was told to leave my documents and that it will be done via the next two days, as it was \to many"for them to do at once. This was at the beginning of September. I have tried to phone them since then 3 weeks now but ALWAYS get their answer machine that says: \""thank you for calling... our office hours are from 08:00 - 16:15 Monday - Friday please call during these hours"
