I placed an order on 24th june 2019 from myntra and due to fit issue... I returned it one product out of three.
And my order no is[protected]-4534101
My return picked up is successful... Got a mail "your refund of amount ₹285 is initiated.
But in actual i got only ₹161 in my account.
And deliberately i seeks for help from your provided number but either provided number out of service or switched off.

Hope you will promptly solve my issue!
