Southern Water Data Breach anyone else a victim?

[Blackcats7]

I am a southern water customer (sincerely wish I wasn’t as they are crap) and they recently had a huge data breach affecting who knows how many customers.
They sent us all an email apology with a link to 12 months Experian membership so we could see when the fraudsters started using our leaked details.
Well the thieves have had a field day with mine. Spent hours on the phone to Action Fraud and have had to do all sorts to try to limit damage done and it’s not over yet.
There was an article in a local paper recently about a group action claim against southern water for those who have been victims of fraud following the breach.
Anybody been affected too?

Yes I had the email and letter, joined Experian using their link

Yes, I am. Joined Experian on the link they provided. Haven't checked whether we've been scammed yet...

I first knew there was a problem when I started getting phone calls from genuine people calling me back as they had a missed call from me. I knew I hadn’t called them and after a few I called Action Fraud who told me this meant my number had been “spoofed”.
I also found out with Action Fraud’s advice that not everything is shown on Experian and I had to join Clear score and credit karma which gave more information.
Had to sign up for property alerts from land registry and join cifas to stop passport/ driving licence being cloned.
It’s a huge worry.

Oh and all the frauds found were committed a month before southern water emailed us about the breach.
