Poor service on fibre line activation

We chose to change our home internet line from ADSL to fibre. The fibre was installed by Vumatell Monday 18 May 2020 and the router delivered to our house the next day. Since then, we have phoned Telkom about 10 times between the Sales and Technical departments. Since Tuesday last week, we have been offline and we have no internet at home. The frustration is that at present my husband is working from home and therefore this will influence our income. We are very frustrated with the process, as everytime we phone the operater tells us that we have to wait 24-48 hours and the only thing that has to be done, is that the order has to be closed off. We have waited 144 hours and still no internet! This is very poor customer service!!
