    @O2 Credit where it’s due that’s a good thing but it’s a Shame I’ve had a poor signal in several places , hit with a 12% hike and told by customer services like it or lump it .

  • confuzzeled1989 Jess Crosby (@confuzzeled1989) reported

    @financialombuds @O2 Thank you so much, I am having issues getting support from @O2 despite having received an email stating they’d remove the defaulted payment from my credit score on 14/02/2022 within 3 working days. It’s still there and was on the phone to O2 for 60 min yesterday with no solution.

  • Cinderella_D Darren Devers (@Cinderella_D) reported

    @O2 very disappointed that I’m being advised your store in a shopping centre only has the capacity to help one customer at a time sending other customers on there way for something as simple as a sim swap. Can a store operate with one person doing work.

  • confuzzeled1989 Jess Crosby (@confuzzeled1989) reported

    @O2 You told me you’d remove a defaulted payment on my credit score on 14/02/2022 within 3 working days it’s still there. I made a SAR and you refused it saying you don’t have data on me, when I go through security each time and have data on me read out to me by customer services.

    @O2 @migranthelp @womensaid I think this is great I really do, but shame you do nothing to help those now facing financial hardship due to soaring inflation, instead you slap a 11.7% price hike on them to compound the problem
