I’ve recieved a couple of messages saying they’re monzo, asking me to update details, but I am suspicious. Are they real? Or spam?
Spam
This is a good help article to help understand/spot scams
Change one letter of ‘spam’ and you get the more accurate answer of ‘scam’.
Someone is trying to trick you out of your money, ignore them. Remember, Monzo have a fully self-contained app that they can push alerts to you through if they genuinely need you to update any details.
And Google Messages is really good at showing the suspected spam warning at the top too
