Said caller was from O2 and needed to send me new Sim card as mine would stop working when tomorrow when 4G switched off. Wanted me to confirm email as needed to send me an email for me to log into. Wouldn't explain when I needed to receive and click onto email why talking to them on phone then hung up on me
