Dr Batra's — cancellation procedure are inadequate

Recently took one year hair treatment package from dr. Batra's, and paid the initial amount of 20000 plus 2000 of emi on yearly plan, inspite of paying the amount additional amount has been paid for the care products exclusive of the yearly package, the treatment has been started off, initially in chennai batra later in kochi,
I was continuing for a while there later after two months, i was again requested to 16k hair vitalizing treatment additional to what i paid before which i said no.
Am not happy with the treatment and it is not efficient for money being paid monthly from credit card, its expensive for me to pay montly and i would like to cancel my year package and i request you to refund the paid amount after deduction for the months in treatment. Am not blaming anyone here! Your treatment is expensive for me.. Which i could to cancel, kindly cancel the plain and let me know the cancellation procedure
