Toothsi — The Company isn't refunding the deposit amount paid after cancellation

Website: makeo.app/toothsi

I have paid 11, 000/- as a token amount for my tooth aligners plan, which I was told is fully refundable after cancellation, but I have cancelled the plan in 3-4 days after the payment and since 7 months there is no refund being processed by the Company, After repeatedly calling the customer support team they just ignore/delay my calls, and convince me to go ahed with my tooth aligners procedures and offer me with discounts, but I just didn't wanted to continue any further with their plan, and not its been 7 months and still they haven't processed my refund yet.
