I believe the drivers are actually calling me from outside of my old place because they basically say "I'm here". The strange thing is that when I lived there, I only got around 3 deliveries per week, and those were usually from my office or Ele.me. The office deliveries always showed up on my phone as "顺丰“ and Ele.me always shows up on my phone as "Ele.me". The grocery store I ordered from when I was in quarantine used "Delivery Service", but those guys have no clue about my previous residence.
