Scam or should I phone bank?

Hi

I just got a text message from NatWest apparently and a voicemail to phone them back as there's been suspicious activity on my account and in the text they list 3 payments that I don't recognise and that my card is blocked.

so I go to my app and there's no notifications about suspicious activity and I always have to approve payments in the app but no notifications for these payments and there not showing in pending nor do I have anything to state my account is blocked.

So I then brought something online to see if my card is blocked because my thinking is if my card really is blocked I won't be able to buy anything but I was able to buy something online and approve it so does this mean that my card is not blocked then?

Could this just be a scam or should I still phone NatWest?

It's a scam.

Likely a scam, but if you're unsure and want to make sure you can go to the official natwest website, grab the number off there and give them a call. Do NOT call the number back that texted and called you, its a very common pattern that scammers use to lure you into disclosing sensitive information.

It was a scam, banks don't communicate stuff like this by voicemail or text.
