I\'m leaving after a month because:

Zen sent a non-working link to their migration order tracker, and didn\'t resolve the issue by mail;

account control is via a portal that requires separate registration. I\'ve been unable to make it work. Support for this has been slow- days to reply to mail;
final show stopper: their SMTP server can only be accessed when physically connected to their network, which means reconfiguring my mail client every time I take the laptop out of the house. Telephone support on this was useless and seemed to think that webmail was an adequate solution.

For what\'s supposed to be among the best I\'ve found them poor.
