They called me 3 times one after another which I didn’t answer as I was eating dinner. I called the number back and it was an automated voice pretending to be the NatWest lost card team
Very convincing, claimed to be NatWest fraud team saying there was suspicious activity on my account so they had frozen it and set a new one for me so I needed to transfer my funds to the new account, when I refused they then tried to get me to give them the 'get cash' code from my app so they could activate the code while my account is frozen. Very convincing sounding, very very dodgy
