Shadowfax — Pick up was done and later QC was changed to fail.

Shadow fax partner had picked up a wrong order of Myntra. Since it was a wrong order (I have ordered a kurta for my elderly mother but instead was delivered a jeans) i did not bother about even opening the inner plastic packing. entire package was returned and later after few hours i get a message from shadowfax stating how QC has failed. After few attempts i could just connect to the delivery partner who put the blame on his senior/area manager and gave his contact number. After numerous calls and almost 24 hours later the area manager answered my call, who goes by name KALYAN and contact number is [protected]. This guy had been outright rude and threatened me with consequences if i call him again and outrightly insulted me telling its your problem that you were not smart enough to ask for QC check then and there. My shadow fax tracking number is R60239416MY.
to top up my frustration with this rude behavious there is no helpline number of Shadow fax where i can connect directly and sort this out.
