    @O2 Hi. I have a problem signing up to my free trial of Disney+. Can you help please?

  • fozzie1960 Chris Foster (@fozzie1960) reported

    @O2 So what is required for someone at O2 to step up to the plate and take ownership of a problem.

  • mark_catling Mark Catling (@mark_catling) reported

    @danny_burton12 @O2 This is poor customer service, Danny! Not how you would expect a global company to treat a victim of fraud. Hopefully you get it resolved very soon!

  • dkinnear David T Kinnear (@dkinnear) reported from Camberwell, England

    @O2 I had a call from Rachel - a fabulous @O2 rep last night to troubleshoot the situation and taking some accountability for what is going on. I’m sticking with @O2 while this gets sorted because of her actions. Great employee who gets customer service and care. 👍

  • Katie59044118 Katie (@Katie59044118) reported

    @O2 truly awful service I have been trying to get my number ported over since wed. I need this for accessing my banking and for my job. Anytime I message you, I don’t hear back and just get the same answer.. wait 24 hours on the phone.

  • EdwardStyle80 Edward Style (@EdwardStyle80) reported

    @O2 @JMitchell1284 I rang customer services this morning and was told to wait for the back office to complete their investigation, no timescales provided. I then asked to submit a complaint, customer service hung up on me.

  • dkinnear David T Kinnear (@dkinnear) reported

    No one could make chaos more chaotic than @O2 - who seem to have literally no concept whatsoever of customer service online, in the store or on the ‘phone. Wasting hours for the simplest addition of a line. Only wish @Verizon was in the UK to provide some real competition.
