How can I get a refund if an e-commerce company fails to deliver a product or delivers a defective product?

If, by chance, a product is not delivered by an e-commerce company or a defective one has been delivered, approach customer service first. If they do not resolve the issue, you can file a complaint with the National Consumer Helpline or directly approach the Consumer Forum under the new act, Consumer Protection Act 2019, where you could be entitled to a refund, compensation, and other relief.
