  • SamCamLlamClam Samantha G (@SamCamLlamClam) reported from Greenisland, Northern Ireland

    @O2 repeatedly ignored by your dms.. been trying to contact you for days - I am incredibly distressed and humiliated by this treatment. Quick enough to get in contact when you want someone to sign up.. not so much when someone wants to cancel their account. Sort it out.

    💡 check your Tesco clubcard account - vouchers for restaurants, Denby dining sets & more - I’ve enjoyed 3 course meals for 2 for like £1.13! 💡 check your topcashback account could be £££ for a M&S voucher for example 💡 If @O2 customer make sure you download free priority app

    @O2 shocking #o2recycle service. Do you now use a scam company? My wife's fully working phone was checked in store and sent off yet recycle say it's damaged. Pure lies. Trustpilot shows this happens all the time. Disgusting and will not take another contract out again with O2

  • lifitz Liam Fitzgerald (@lifitz) reported

    Honestly @O2 need to sort their customer services out. 3 calls transferred and cut off, 4th call was advised I wouldn’t be transferred/cut off, was placed on hold for a further 45 minutes and then call disconnected. #bye

  • geordiepam Pamela Berry (@geordiepam) reported

    @O2 disgusted with you O2 been a loyal customer for over10 yrs and you cannot waive a measly £107 off my old contract so I can upgrade today - yet you did it for my wife twice at £120 left on her contract can’t override your system what a joke
