La Pino'z Pizza — Refund

Hi,
I had ordered a pizza from La Pino'z, Pali, Rajasthan.
The restaurant accepted my order though there was no electricity.
Since I didn't receive my order, I reached out to the restaurant demanding my refund where they requested me to wait till electricity is back.
After electricity was back they said they have cancelled my order and refund will be issued in 6 days.
When I checked the app yesterday, they had marked my order as picked up.
The owner told me he would refund the money after 6 days but I didn't receive any message or confirmation.
