Bad business ethics & poor customer suppport.
The software itself is great, however their business ethic and support teams lack any real care or aid in your needs and situation. There is also a very trap-type feel to their subscription, along with lots of comms for the confirmation of subcriptions/payments but nothing to notify you of upcoming subcriptions/payments. I was upset as well in their priority in taking customers' money but no concern to if the customer was getting value for money.
