Myntra.com — return of a clothing product

Address:

Varanasi, Uttar Pradesh, 221010

I recently purchased a pair of blue jeans from myntra. The jeans did not fit me properly and so i requested for return.
However, it has been 10 days already since then and no attempt for pickup has been made despite my repeated complaints to the customer care as well.
Everyday i call the customer care and tell them about the issue. They tell they would look into the issue but no actions has been taken since then.
The pickup partner assigned for this is xpressbees but they also do not respond and have provided me with an invalid contact no.
Please look into the matter as soon as possible.
