Myntra.com — Return product was picked up by agent but no update from myntra

My concern is on 24th aug 2021 I've placed return request and on 25th august 2021 at 2:55PM delivery agent from EKART picked up order after that I didn't any SMS from myntra or EKART that order was picked up. Today is 30Th August still didn't get any update and on myntra app the status is not changed that item was picked up. When I raised concern n myntra app they are asking for pick up sms acknowldegement. From where should I get it. Please contact with EKART and process my refund.
