Amazon India — Escalation on Nokia phone return

Hello,

I had purchased a Nokia G 21 and the phone started showing some random coloured lines on screen. I requested for return so Amazon scheduled one technician visit. Technician came and confirmed that it is a manufacturing defect. So, Amazon is rescheduling the pick-up all the times but agent is not taking the phone back. He is saying line is not visible and after switching on the phone it is asking for PIN. So, that is default feature of Nokia. And, Amazon people and pickup agent are not understanding it. They are only rescheduling the pick. That is really pathetic.
