Thank you for taking the time to reply. Our sessions we always based on skype . but I only saw him in person for the past two months. I didn't officially sign anything.This was from the first email he sent me: "Please think carefully about whether you are able to commit your time on a regular basis as you will be charged even if you do not attend your session. If you talk to me in advance of any absence, it may be possible to reschedule subject to availability. I will inform you of any breaks that I intend to take in plenty of time. "

I'll email him but i'm not sure if i'm making the right choice.
