    @O2 disgraceful customer service when trying to sort out my son who has Asperger’s account. Taking extra payments and then hang up in their customer. Well done O2

  • MrsDaveGahan Julie Ball (@MrsDaveGahan) reported

    @O2 very disappointed with your service. Unable to get consistent signal via hotspot. Tried to cancel due to lack of consistent service only to be told I will be liable for remaining charges. It would be nice to speak to a human!

  • hughesclaire39 Claire (@hughesclaire39) reported

    @O2 Time doesn’t matter when you’re with @O2 as you never have any signal anyway. I sleep soundly every night!

  • Jameseo23 James (@Jameseo23) reported

    @O2 Any reason I can't make a call from Japan using my PAYG account? I topped up but every call I make says I have no balance, even to your free customer support numbers. My top up was successful.

  • _carljenkins_ Carl (@_carljenkins_) reported

    Hi, @O2...yet again no signal and stuck on emergency calls only. If you can let me know how long I have on my contract so I can end it and switch network provider, that'd be ******* great 👌👍

  • _JHedge Jill (@_JHedge) reported

    @O2 Spent 2 hours and 45 mins on hold today with 3 calls being cut off by O2 agents. I’m trying to clear up a mess that was caused by O2 that is having a severe impact on my credit score. Also no reply to my DM, I will never be using any of your services again.
