Mweb not quite what it seems.............

Being a customer for over 20 years changing over to fibre with mweb continue to provide internet has proven a complete nightmare. Its over 3 weeks and the internet not operating, endless calls to no avail. They even logged a specialist support person will call me at an agreed time but nothing, no channel to escalate - emails do not get responded to. No facility to leave message if we run out of airtime. Just a very bad experience indeed. I don't know if I will be connected .............
