Club Mahindra Holidays — Cancellation of membership and get refund

I was invited for orientation from Vishnu cars and club Mahindra people provided incorrect information and made me to join. Later due to covid I post my personal member and I'm in a huge loss, but CM have been taking out EMI by auto saving my credit card details without my knowledge. I need to cancel my membership and need to get full refund, as I'm not in a intention to go out anywhere, also the service I received from them via phone and emails were pathetic.
