Nykaa.com — refund not received yet

I have placed an order on nykaa on 6th april 2019 but didnt received a single product till 29th. Then i cancelled the order on same day but its been more than 2 months now i have not received my refund. It was a prepaid order. I called the customer support almost 10 to 12 times but what i got from them was the fake commitments every time. Every time they said just wait for 24 to 48 hrs and u will get the refund. I am frequent buyer from nykaa but this time i am really disappointed from this kind of service.
