That's true and lately they (scammers) have developed lots of ways to reap others of their hard earned cash.
Few months back a guy called me, he even mentioned my name saying my sister is sick and has been rushed to the hospital (he was also faking a cry)
When I asked him my sister's name then he changed to abusing me.
I'd advice everyone out there to be careful with every single transaction they make, before sending money to anyone confirm if it's truly their account and also be watchful on the links you use as they can hack your phone or account through links.
