Poor customer service

Vodacom immediately disconnected my fiber installation, for almost 4 days and informed me that they had given me the wrong fiber or internet. I have spend huge amounts of money trying to resolve the matter and the consultants were very unprofessional, and they did not seem to care about the issues I had. I have not yet since had internet connection but a full payment is expected from me. I am working from home and I am struggling to stay connected to the internet and this is a problem for me coz my job is also on the line
