Pizza Hut India — Doesn't get refund even after 4 months

On 24/09/2022, I ordered 2 personal sized pizzas from Pizza Hut. I had to get the delivery done, but due to a mistake, I made the takeaway order, then, I quickly called that Pizza Hut outlet and asked if this order would be delivered to my home. Maybe then he refused, then asked to cancel the order. Then I asked about my refund. He said it took 1 week but you would get your refund. From that day till today I have not received a refund and I'm still trying to get a refund somehow.
