    @O2 is your service for SE12 down? Can't make calls, use data, or send texts. Your outage map says it should be fine but it's not. Really frustrating.

  • FlooringJdk JDK Flooring (@FlooringJdk) reported

    @O2 do you have managers anymore? Been promised a call back twice and still hasn't happened. People should use @ee instead probably get better service
