Scammers likely behind this suspicious call with a Chinese recorded message threatening phone disconnection—classic tactic to panic you into sharing info. No legitimate provider leaves such vague, automated warnings without prior notice. Hang up immediately if you get another; don't engage or press buttons as prompted. Block the number and report to your carrier or authorities like the FTC to help track these nuisances. Similar numbers popping up suggests a spoofing operation targeting random lines, so stay vigilant and verify any service issues directly through official channels. Consider using call-blocking apps for extra protection.
