MWEB horrible service

We've been with Mweb for over eight years now and recently moved into a new apartment and so the line has been moved, we decided to upgrade the line to a 20mb fiber line and organized for the installation on the 4 of April 2019. SADV came to install the fiber line about 2 days after we requested it and we waited about a week or two after that for mweb to give us our login details and send us a router, The net was only working on the 14th of April they sent us an outdated router with problems where it would switch off the WLAN automatically despite long hours of technical support the problem still persists yet Mweb wants to charge us for the whole month despite not having had access to the internet for the first half of the month as well as the line under performing and only giving us 10mb speeds. We have logged multiple faults with Mweb they have only told us that they will replace the router and we have not heard back from them since. We are now stuck with a faulty router and an under performing line in a 12 Month contract where we are yet to see Mweb bring their part.
