If you only ever paid them the one time fee of $2700 and are never planning on giving them any additional money, and you saw a benefit from it, no problems.
If they've hooked you into signing up for extra classes or special coaches that are going to cost you more and more over time, you should try to take a couple of hundred steps back and look at it as you might look at scientology.
BTW: still waiting on my signed book from placing in the top 20 in the WSOP challenge last year.
Good luck in poker this year.
