Ekart Logistics — Hot n cold water flask

I ordered a hot n cold water flask from flipkart. Product delivered. But product is very cheap quality and damaged. So I put return and refund request. On website they mentioned pickup date after 4 days. But pickup boy called me on next day for pickup. But I was not available that time. I asked him why u mentioned late date on mail and app. Then he promised me to reschedule the pickup. But no one contacted till my pickup limit days passed. Very bakwaas service
