Discovery mislead you and drain your pocket

Good day I am sad to say that Discovery health are misleading people on their weight loss program. They give you an option of signing up for 3 months or 6 months. I chose 3 months as this was all ky budget would allow. Well they took off a 4th months payment of R395 off my account. I was then told to read the small print where you have to give a months notice which I did. I was told by the dietitian that they received my cancellation and no further money would be taken. Well today a 5th amount of R395 was deducted from my account. I have now paid almost R2000. Why was I given the option of signing up for 3 months if Discovery can just continue taking money every month. I cannot accept this and need a refund of 2 months R395. Supposedly they are interested in our health!! I'd say ***** and Increasing One's stress levels while their bank balance increases.
