An e-commerce seller in Kolkata refused my refund for a defective product; what are my rights?

Refund refusal for a defective product is unfair trade practice under Section 75 of the Consumer Protection Act, 2019 and the e-commerce rules framed thereunder. File a complaint with the District Consumer Forum in Kolkata and on the Consumer Helpline portal, attaching the order ID, photos and the seller's refusal message. The e-commerce rules require the marketplace to display a clear refund policy and to honour returns within the stated timeline. The Calcutta High Court can be approached only after exhausting the consumer forum remedy, except where the seller is unreachable or the platform is complicit. West Bengal Premises Tenancy Act 1997 consumer protection rules may allow a faster direct complaint to the State Consumer Disputes Redressal Commission. Preserve the product, its packaging and the chat with the seller as evidence. You can also rate and review the seller to deter similar conduct with other buyers.
