Help, I've been ripped off by Dorra Mid Valley

[Chinky08]

Last Jan 19 2019, i went to Dorra midvalley for a free trial, a consultant went into the room and discuss about my weight loss program, initially offered me 40 sessions for 11,000 RM but i refused, until it went down to 3400RM for 10 sessions, they even said they can put 0% for 36 months on credit card. I really dont know what happen why I agreed,i gave my credit card. I also agreed for another 10 sessions for another 1400rm. As soon as i went home, i realized what I did and want to cancel, but when they called me, they said they wont since its non refundable, I ask the cancellation terms were not discussed and they forwarded a form which i recall to have signed. Please help me, i was pressured from their torture selling, i need to get my money back
