Myntra.com — Fake FOSSIL watch delivered and not refunding my amount

I had ordered a fossil watch Order ID # 1220764 [protected] with Model name FS4656, however, FS4656IE was delivered to me which is a different design and model number also. ON return Myntra denied saying quality check did not pass wherein they in the first place have delivered a FAKE FOSSIL watch. My order amount is Rs 9, 715 which is a huge amount
Myntra have been calling me and mentally harassing me as well
I want to charge them for my refund amount as well the mental harassment legally
Please have a look at the watch design on the app for this Model and the images I have shared
