Sandals delivered in opened package so sent for return and refund on 19th June.
Constant complaint had been sent but got no response.
It's been almost 2 months and we haven't received any messages or refund yet, this Is a shame to the company.
I demand quick action to the earliest.
The courier company had delivered the package opened and was not ready to take the blame and neither does Myntra.
What should a customer do who's spending the money for such a big name?
It was a very big disappointment
