Need suggestion on Pepperfry furniture return

Easy. That email is your ace card.

Just tell them, I shall raise a chargeback with bank to get my money back. If you don't want to lose both money and furniture, better take it back.

Furniture return is a hassle and expensive. But the onus is on Seller/PF because they have sold a defective piece without proper QC in the first place.

All the best
