Myntra.com — return not picked after days, phone call not received

Address: Kamrup Metropolitan, Assam, 781003

Website: Myntra.com

I initiated a return request on 25 december with return number [protected] on myntra. The order was supposed to be picked up on 26th december. When i called the pickup agent, he said he will pick up on 26 itself but instead i got a message later saying since i requested for reschedule, the pickup attempt failed and will try again tomorrow. When i called again, the guy said he will pickup tomorrow so i waited for the next day and he again said he will pickup but didn't. Now he is not accepting the calls and myntra is not updating my return process so i have no other way to return the parcel. Please help me. The delivery agents number is [protected] (Assam). I feel like he has been ordered not to pickup the parcel by myntra because normally, they come for pickup. This time he has given many excuses. I cannot even use the product because it is oversized and it is of high cost and i definitely want a refund.
