EMAIL SERVICE UNAVAILABLE

As from midday our business email provided by Mweb became unavailable due to one of their servers collapsing - DO THEY NOT HAVE BACK UP? 5 hours later we still have no email and very little business left. There is nothing on the Mweb Home page about the problem. I guess that would be taking their customers too seriously. The only way we found out about the problem was to phone - not their support number - that does not work - but to phone their sales number and hang on for about 15 minutes. Only then did we establish that there was a general problem. Unfortunately changing email addresses is not that easy - otherwise we would move to another service provider. Perhaps a smaller service provider that still takes its customers seriously.
