The provided information suggests that the caller is likely a scammer, using a common tactic of claiming a delivery attempt to lure the recipient into taking action. The mention of piano music in the background is unusual and may be an attempt to create a sense of legitimacy or distract the recipient. The fact that the recipient is not expecting a parcel further supports the idea that this is a phishing attempt, possibly aimed at gathering personal or financial information. The use of ups as a supposed delivery service adds to the scam's credibility, making it a relatively sophisticated attempt at harassment.
They claimed a UPS delivery attempt with background piano music, yet no signature was obtained and I wasn't awaiting any package.
