Caller: An Asian male who claimed to be from Mastercard security

He claimed they had stopped an $1800 payment to a woman overseas for cryptocurrency. I don’t have a credit card but he tried very hard to convince me the bank had made the payment but they were holding it. I told him that he wasn’t getting my personal details and at that point he hung up. This is the second time a similar number called me but it’s the first time it wasn’t a silent call.

Getting calls everyday from numbers starting with 02 7248 last 4 numbers change each time. No message left. If I answer I can hear a series of clicks and then they hang up
