Swiggy — i received fake calls from the person who delivered the order from swiggy

Hi team, me and my friend came from office late. So we ordered food from swiggy. Once i ordered the food i got several calls from the different fake nos.. Attached is the screenshot of phone no. From which i received called. I am afraid they know my address nd my phone no. As well. Moreover they also threatened us like why we are in room. I am totally disappointed from the services of swiggy app.. I m really unhappy and will not use this app again and will. Not advise any of my friend to use this app
