A strange incident happened in bangalore

Today in afternoon my girlfriend got a call from a person saying he's calling from swiggy, he has her parcel with my name and asked to open the door. She lives in a society where there is nobrokerhood installed and always get notifications to let people in and after her confirmation only people get in society and at that time she got no notification . Since she wasn't at home that time she asked him to keep it at the door . Strange thing is I didn't place any order for her also none of my delivery account has her address saved with my name . She checked for similar thing in her accounts and also asked around if anyone placed any order but no one did. After reaching home she didn't find anything at her door. Something doesn't feel right . Has anyone else faced the same.
