Worst service ever

By far the worst Wi-Fi service provider experienced. I opted in for the Wi-Fi after attempting to move with my previous provider, unfortunately the area I'm now staying in supports this company. After receiving my router i wanted for almost 10 days for the router to be installed. Today it was installed and the tv in the same lounge area as the router does not pick up the 5G I'm told i need an extender. 30 min after the technician left the Wi-Fi stopped working, i immediately called for assistance, and I'm now told i need to wait for 3 more days minimum and someone else might call to assist. So it's now going on to 3 weeks since i signed up for the product, and yet have not had the opportunity of using the actual product.
