Myntra.com — myntra refund problem. i don't get my refund amounts

Address: Kalathumpadi house, Vazhampuram post, 678595

Sir,
I had purchased a shirt and trouser from myntra, hrx trouser and harvard shirt. The size was not a fit and the colour is different, so i decided to return the product. They picked up the item but i still didn't get the refund. Also got a msg from myntra saying the refund has been initiated, but even after 7 days, no further update. I tried calling their customer care but the call would not connect. Order no and return number included photo given below. Please take an action. I am student.
