Reebok India — Partial payment of refund

I had ordered a set of 3 masks from the reebok website of Rs 799 on 2nd December 2021. But i had cancelled the order on 5th December 2021 before it dispatched by calling there customer care. I recieved a confirmation stating that the order stands cancelled and i will recieve a refund. On 7th December 2021, i recieved a refund of Rs 100 from there side whereas the order value was Rs 799. I again called there customer care and was asked to mail my issue with the screenshots of the payments which I did and received no reply. Today is 2nd March 2022( 3 months from the day of purchase) and haven't got my 700 rupees refunded even after complaining for 3 months. Wasn't expecting this from a company as big as Reebok.
