I managed to get one of those guys to talk to me "honestly" for a while. He started his patter and I said I knew this was a ransomware scam. I politely asked what his plans in life were.
We played a little guessing game about where they're based, since the accent is obviously Indian-subcontinent. Took me a couple of tries, but the answer is Sri Lanka. I suggested he learn to program if he wanted to have a more successful career.
The next time one of them called I asked how the weather was in Columbo that evening and blew his mind a little bit.
