Had a missed call from 2 different numbers. Voicemail left both times saying “to discuss a job with you please add my number on WhatsApp”. I’m a plumber so first one seemed odd but possible, second one got me questioning. Different number but definitely same voice in both voicemails.
Anyone heard of a scam that starts that way, not sure what the angle could be, obviously if they have my number and want to discuss a job they could just WhatsApp me directly? Don’t get the add my number on WhatsApp bit
