They make you jump through hoops not only to cancel (several, annoying hoops), but I even had to badger them for a week to find out how much it would cost to even UPGRADE. Their customer service is so outstandingly, and willfully, terrible, that I went out looking for alternatives, and I found several that are much better - namely 'Commun.it'.

Don't get this. All I can say positively is that it's literally better than nothing, but not much better.
