VOIP not working for 4 months - all calls ignored, no call back, yet they charge me

It is now 4 months since I ordered an additional VoIP service from MWeb with a phone supp**** by them and it has not worked since day 1 - in spite of me having another VoIP service from them that works perfectly with the same setup but using a Fanvil phone I already had. The reason is that the Yealink phones Mweb supply don't work with the Mweb service and THEY KNOW THIS yet keep on selling them!!

I have called the MWeb technical call centre and customer service dozens of times - each time having to go through the whole story with the service agent that takes my call - it's not possible to speak with the same person more than once.

I've always been told that my complaint / problem will be escalated. In the early days (last Nov) technical people did call back and changed all my settings, sent me a series of replacement phones, etc. Nothing makes any difference - their service just does not work with Yealink phones. So over the last two months they just ignore me but keep on billing me! I have tried asking to speak to managers in customer service or billing or technical to try get a refund or some other resolution but NO-ONE EVER CALLS BACK. When I call in again I find the previous ticket has been closed even though they never actioned it at all!!

At the end of each call you are requested to rate the service that you received - often the person in question deserves a positive rating because are just the front line person who is logging a ticket for escalation. But what is the point of that if there is never any further action? So if I was ever asked for a rating for MWeb overall - that would be a big fat 0.
