Can a complaint filed against a company under Section 138 of the Negotiable Instruments Act be valid if it's signed by an authorized representative but lacks verification?

Under Indian law, you have the right to seek a full refund if the builder fails to deliver the promised flat. You can file a complaint with the Real Estate Regulatory Authority (RERA) or approach the consumer forum for redressal. If they refuse, you can also file a civil suit in court to claim your refund.
