They call me every several days something 3 or 4 times a day sometimes they leave vague voice-mails saying they need to get in touch with (they don't even know my name or where I am or what they called me for) so it's clearly a scam and those kind you must hang up asap before they collect more data without you even needing to talk they can still enter your phone and steal data and valuable info! HANG UP IMMEDIANTLY better yet don't XXXXXX answer at all
