I received a call from my "bank support line" a while ago. Now these people were real con artists, they had all my data, used correct chat scripts etc. It all sounded so legit I almost missed the moment they asked me for SMS confirmation code, at which point I realized it's a scam. Not being sympathetic to these guys but at least they were highly professional and inventive scammers, unlike those I mentioned above.
There is one I heard of recently, the scammer will call you, telling you about the school of your child, the scammer will be posing like a worker from the school. It will tell you there is a parents teacher (PTA) meeting going on, that it is very important. He will tell the person that he will receive a code that will be sent to his mobile phone number, that he should tell him the code so that he can be able to link him to the meeting going on. I have seen people saying this has bee used to scam them in my country.
Somw people falled for this scam just because it doesn't want to look like scam until they are scammed, even if the call is from the school, the person need to use the official school number to call the school before proceeding doing anything.
Some of the victim says they later called the school, telling them if true about the meeting, but the school will tell them there is no ongoing meeting. But because the code has bee sent, they scam is already elicited and successful, this is done in a way money is withdrawal from the victim's account number.
Although, this is not totally crypto related, but it is worth knowing, that will should not click on any of such link, not to talk if telling the caller the code sent.
