Terrible Service Received from MWEB

Mweb became our fibre service provider on the 11th of February 2019. We have had issues from the start, we notified mweb that the router they had provided wasn't providing us with a stable wifi connection (the router would disconnect and reconnect every 5 minutes). Mweb staff insisted that protocol need to be followed and the router could not be swapped out, after daily phone calls we followed the protocol for a month and were still being told they need to "monitor our connection", Eventually we thought we had some joy as in March mweb agreed it was the router and would replace it, after waiting again for the new router we received a REFURBISHED router, this had no internet connection at all, which was two weeks ago, we plugged it in only to find out this router doesn't provide wifi at all, we contacted mweb on the same day the new router was delivered, to date they are still promising a new router while we pay them for a service which we are not receiving. Truly a terrible experience as well as terrible ISP . Its as if as an mweb customer you are asking for to much if you expect to get good service or to simply receive the service they are so timeously able to expect payment for.
