Myntra.com — return not being picked up or processed and cancelled randomly

I have placed a return request for 1 product i had bought. Initially the return was requested on 24th may. After few days of waiting, this request was abruptly cancelled by them on their own without any kind o[censored]pdate or intimation. I again placed return request on 8th june which was not at all looked at again for many days. I raised the issue on twitter on which i only got regular autoresponse saying someone will connect with me. Yesterday, someone just called me to say that no one can come to pick up the return for which when asked about the reason (Since all deliveries, etc are happening properly), the person didn't have any answer. The person randomly said that my area is non-serviceable. If it is non-serviceable, i would not even get any deliveries in the first place right? And then, again, today my return request is randomly cancelled from their end and the issue in the app is marked as resolved. I am not understanding what am i supposed to do. Also, the person who had called me said that she is the highest authority for complaint resolution, which is difficult to believe since she was not at all aware about the whole situation and only kept speaking scripted lines to me despite whatever i was asking.
