Amazon India — Faulty duplicate item delivered

Ordered a watch worth 7k on 3rd March. a faulty duplicate watch delivered on 6th March. Raised a complaint on the same day of delivery. Raised the issue in their Twitter handle as well. Since then nothing happened. Many mail communications and calls are made to their customers support team. Item is denied to pick up by pick up guys for 9 times. Issue is not resolved for morethan 45 days. Order number for reference[protected]. Hope my voice is heard and some solution is offered.
