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.
This type of scam is more common in my region I don't know how these people are able to get our information data from the bank, they know so much that if you are not a security-conscious person you will fall for their tricks and before you realise your account balance is wiped out in a sec, .
It takes a lot of courage to to avoid been scammed
It has happened in the past that some banks have shared creditworthiness data with third parties. Therefore, it is possible that scammers are able to access data from the bank in this way. For example, when I was having trouble paying off my bank loan, I started receiving offers from other banks to reschedule my debts despite the fact that I never asked them to do so. There was no doubt that the banks shared information among themselves. Also, some bank employees who lack adequate training may accidentally divulge your bank information to third parties.
