Recently I've gotten a strange incoming call from an unknown international phone number when I was connected to the Net through Wi-Fi. I rejected the call. After several seconds this has repeated.
I've decided to check if this number is bound to WhatsApp account by adding it to my phone contacts, but this number doesn't exist in WhatsApp! I would like to know - has anyone encountered this situation and what could it be? Any help would be greatly appreciated! Thanks in advance.
