Misleading product representation and delayed product delivery, cancellation and refund

I placed an order with Sangeetha Mobiles on 17th May 2025 with a 24-hour delivery promise. The product was not delivered and is reportedly not available with them. I formally cancelled the order due to their failure to deliver and lack of stock. Despite multiple emails, cancellation and cancellation/refund have not been processed. It appears they are stalling cancellation., may be to procure the product from a third party. This has caused me mental distress and I am considering legal action.
