MWEB is a NO-WEB

MWEB recently moved their email service (that I pay for monthly) to a new platform. The ongoing process is painful with several emails not delivered to or from me. I tried the link they provided for such problems and got this reply:

This inquiry must be redirected to our Support team.

And they can only attend to the query; they are unable to check the issue for clients

and

This ticket is now closed, DO NOT REPLY

This from the link they provided for issues.

The non delivery of my emails persist and the attitude of MWEB seem to be that I must fix it.
