Inefficient Service & Non Delivery

I've requested a transfer of my fibre service from one unit to another unit in the same complex in the last week of April & the technician was out on 06May to setup & plug in the router. Since then we have been waiting for the internet connection to be restored & I've called many times but still nothing is done and no body calls back with a solution or turnaround time. It seriously cannot take almost a month to reconfigure a router or have the decency to call the client back
