Byju's — Cancellation of Courses / Product

I was purchased the product two months back i.e., 2nd week of February 2022. I faced a problem regarding Byju’s online classes and same conveyed to his representative for resolved the issues. But my issues are not resolved. Then I requested to cancel my product through text massaging (What’s app) to sales person (Mr. Mayur Sharma) on 1st March 2022 but it is not cancelled. Again, on 22nd March 2022, I requested to cancel my product but till date no action taken from Byju’s representative and on 07th April 2022 he deducts 1st EMI (Rs.8333) from my bank account and Rs.10, 000/- given to sales person at the time of admission. My child is not able attend any classes as no classes have been arranged for him about 1.5 months. Now I don't want above product because nobody will be responding. Please cancelled my courses (product) and refund the amount.
