Experiencing problems with Vodacom's Fibre

We have recently taken out Fibre with Vodacom and till date we still cannot connect. (Vamatel) The installation has been done on the 27th of May. We have been logging calls but our problem has still not been resolved. They say they will call back but no one ever does, you must call again and spend wasted time on the phone. They cannot put you through to a manager or even give you the manager's number. This is totally unacceptable
