Address: 411028

I ordered from myntra and returned 7 items of more than 7 thousand rupees.in spite of me calling them every day, they are not helping me with my refund amount. Action should be taken against them. They are asking me to contact the bank but what the bank will do if mynra will not transfer the money to it.
I have talked to their escalation team many times as well, first, they said we will get back to you and now they are saying we cannot do anything with this. Please take my complain and take action against myntra.
