Order not delivered

I am first time customer and bought a 55” TV with 42K on 13th April. The promised date of delivery was 17th April 2021, they postponed to 19th and again postponed to 21st saying there was weekend. Since then I have no update or no idea where my order is ? I called the customer services several times, they are just horrible and are not at all bothered about solving the issue. I am feeling very disturbed and looked like an idiot paying money to them.
