Pizza Hut India — Refund not received even after 1 month

I had ordered some items for Rs. 307/- vide orde no. 16002436 dated 05.08.2023 but the order was not delivered and I was informed on call that I would get the refund within 7 days for this undelivered order. Till now I haven't received the refund. I have tried all possible ways like messaging on Twitter, contacting toll free no., trying to reach Store manager who is just not picking up my calls, but I have got no help from anywhere. Kindly refund the amount as already 1 month of time has passed.
