If I get a call from a number I don't recognize I let it go to voicemail. If it's important they will leave a message. They never do.
1. If you get a text message with a hyperlink, just delete it straight away. 2. If you are sending money by internet transfer, first send a small odd amount and only send the balance after you have phoned them up to confirm they have received the first payment. 3. EDIT. I never answer a phone call from private number.
And when the bank send you a contactless debit or credit card, cut a 6mm "V" at the centre of the top edge to break the inductance loop, then use the chip and pin function.
Sorry I can't make more of a commitment. I just won the Nigerian lottery. Need to send $100 to get my prize.
