Hair Club For Men

I went for a consultation to The Hair Club in Atlanta, Ga. last month. Before I knew it they had me in there for my 1st treatment and during that time had me sign paperwork which I had no way of reading while the treatment was being given. Now I have a credit card charge of over $3000. I had the understanding that I would be paying a monthly fee for 12 months but this is not the case. I have only received one treatment but owe $3000 regardless of whether I continue. This is not fair. I feel I have truly been scammed. Do I have any recourse?
