    @O2 I need to escalate a complaint re. a member of staff who refuses to to 1) process my upgrade and 2) who has just terminated my call. Who can I talk to? Your staff say it’s not possible to talk to a manager.

  • HerbieMont Herbie Mont (@HerbieMont) reported

    @O2 This is really not good enough service. Call centre told me they can’t help. Web chat said it would be done by now. Twitter is taking days. I’ve been without phone since last Thursday evening, I am going abroad on Friday. No phone and no support. Why should I stay with you?
