Pizza Hut India — Ordered cheese burst pizza received pizza without cheese

I had ordered small cheese burst pizza and then they sent us pizza without cheese. After calling their toll free no. The pizza Hut manager set we will send another pizza as he was at fault. After I disconnected my toll free call as I thought I got resolution again pizza Hut manager called me and asked me if I want a refund or another pizza. As it was too late for another pizza, I agreed for refund. He said he is waiting for OTP and I will get message for refund and refund will get processed within 7 days. Still I have not received any msg 8/09/2021...time 11.35 pm
