MWEB - APPALLING LACK OF SERVICE

I suddenly was unable to send emails from any of my devices, so clearly an MWeb problem. Tried calling and had the phone put down immediately so decided to try a chat. It took 2 hours, yes TWO HOURS, for anyone to respond at which point I was told that I had been deactivated. No explanation, no apology, and a casual estimate that it would take at least 24 hours. All this while I am fully paid up - because MWeb ONLY accepted debit orders when I signed up 30 years ago. When I asked why this had been done, they cut off the chat.
