i did not post it but the person is saying that he got my number from canada visa forum and he was calling from California it showed in my true caller.
time to quit the whatsapp group which u joined where this person got ur phone number. he/she may have joined the same whatsapp group ur in and got ur number from there
be careful about what u post on social media. As a rule never give ur phone number, birth date , ur credit card details on any social media be it whatsapp or candavisaforum. never give ur personal information
