Mobile account suddenly doesn’t exist

For some reason today I can’t make calls or send texts and according to the plusnet app I’m no longer with them , no idea what’s happened

Hi there,

I'm really sorry to see your mobile's stopped working.

I see the issue but I'd need to go through our security checks with you first.

Could you private message me your full name and mobile number to start with?

Hi there , I’ve private messaged you,
Thanks, Simon.
