Mweb's poor service re mailbox migration to new platform resulting in mailbox/email ceasing to operate

Mweb has informed me that my mweb mailbox has been moved to a new platform. Since receiving their email I have been unable to send or receive emails. I went on to the Mweb website to try to find out what is going on, simply to discover that the website cannot locate my account (despite the fact that I have received an invoice for January 2026, which was paid by debit order on 31 December 2025). I have sent emails to the email address that Mweb provides for queries about the migration, ***, but without any response. The problem remains. I am now waiting for technical assistance on Mweb's technical helpline and have in 30 minutes progressed from "caller no 11 waiting to speak to a representative" to caller no 8. This is utterly unacceptable. I don't have the whole day to sit around waiting to be served.
