Don't trust anyone if you still don't know who they are.
It all started when the guy got the phone number of a relative to ask for money. I had just woken up, and well, my grandmother and my mother fell for it and said they would send money. They already sent 20,000 bolívares and 35 dollars, all in bolívares. So my advice is always to call your relatives and verify completely who the person is by asking them to send an audio, a message, or a video of themselves.
