I've been receiving a large amount of scam calls telling me that "My Royal Mail Express/Evri/DHL/DPD/etc package is at the pick up point" in a strong Chinese accent with "press 1 for English, press 2 for Chinese." For a laugh, I'll press 1 and hear music before Chinese is spoken (Couldn't tell you if its Mandarin or Cantonese) and I'll ask "Do you speak English?" Before the line hangs up on me.
I've also received a call telling me "This is the Immigration Bureau, your visa has expired. Press 1 for Chinese. Press 2 for English." I pressed 2 for a joke, and was greated by a Chinese accent speaking English. I said "You're not the Immigration Bureau as you're ringing from a mobile number, not a landline." The caller said "Yes this is and your visa has expired." I said, "That's funny, as I'm a British Citizen living in the UK." Before the call ended.
