KFC India — Unauthorised location tracking of an individual

Recently, I have visited KFC - Jipmer at Pondicherry on July 2, 2022. My friend paid the bill. After that, the next day I received a message to phone stating that to give a feedback on my recent visit to KFC - Jipmer.

Though my friend paid the bill and in any cause I didn't involved in giving my number for the bill process. Then how do I received that feedback message with exact location I visited. I didn't even have KFC app in my phone or browser logged in. How can be this is possible to know my location?
