Imagine your email routine. You log into your email and sit back to tackle your correspondence. You notice with some pleasure that there is a lot less spam than usual, and note that there generally is a light load to address. But then suddenly the mail you were about to read is gone. A few minutes later a few messages appear again and you start reading them. Then, boom - they are gone too. Panic takes hold.
This is the sort of thing that we all imagine can't happen to us - but is possible, and it did happen to a Kabissa member this week.
