Everything is a struggle with this system. I've been using it for 14 months and every step of the way it's been torture. I'll be moving on to a new system as soon as I can get all the customer data downloaded.
The setup is way too complicated, and unless you are on the expensive plans, they do not offer any kind of phone support. The email support is shoddy beyond belief, in fact I've been dealing with a simple issue for over 2 weeks which shows no sign of resolution, purely because my agent is too incompetent or poorly trained to understand the situation, in spite of it being explained multiple times.
Do yourself a favour and go somewhere else. If you find somewhere good, let me know and I'll be right behind you.
