Saint, I get many phone calls and emails from people trying to scam me but it's been many years since any of them succeeded. When I first signed up for the internet some time in the late 1990s I got an email the following day from the ISP wanting me to confirm my credit card details for the charges. I replied as I hadn't been aware of that sort of scam. But afterwards I wondered and I got in touch with the ISP and they confirmed it was a scam. So I got in touch with the credit card company who froze the account. Luckily I had done that before the scammers did anything so I didn't lose any money,
But that experience made me very wary of suspect phone calls and emails.
