We have been a GrooveHQ customer for over a year, started as a "free forever" account and got tricked into upgrading 30 days later.
Since the whole thing was easy to setup and we have only 5 users, we started paying the $15/user/month... Now, imagine my surprise today (07/27/17) when they started charging us $22/user/month!
That is a 50% increase PER MONTH without notice.
They went from "free forever" to "$15/u/m" to "$22/u/m" without a single explanation or communication to the customers.
I'm out and I would recommend anyone thinking of becoming a GrooveHQ customer to think about this:
You don't know how much this is going to cost you next month! Don't let their marketing skills fool you, they are as shady as it gets.
