During this past summer (2008), I contracted ($464)with Amadeus Home Music School for 8 guitar lessons for my daughter. Towards the end of these 8 guitar lessons, they charged me ($464) for another 8 sessions without me ever having signed a contract for the additional sessions.
Since my daughter was about to start 10th grade, I was not ready for her to continue the guitar lessons until I felt assured she could keep up with her school work. So, I complained via email that I had not agreed to any more lessons. They said that they'd look into it. Weeks went by with no response from them.
I sent another email and they said they were still looking into it. Then, the contracted music teacher agreed to call them and tell them that he never provided any music lessons past the first 8 sessions. I sent them another email, and again, they told me they are looking into it. At this point, they don't even bother to respond to my emails.
Beware of these folks.
