    @O2 Hi I’ve switched my gran switched from pay as you go to pay monthly and her phone number still hasn’t switched can someone help

  • BrendanB2 Brendan Bonner (@BrendanB2) reported from Belfast, Northern Ireland

    @O2 I wouldn’t recommend anyone buying online and redeeming your phone. Go to the store, you can’t trust any of the online and virtual services. Was a handling getting phone set up, getting help and they only give you 50% of the value they say (no matter how good your phone is).

  • thebaldfather Hugh Pollock (@thebaldfather) reported from Belfast, Northern Ireland

    @O2 I am amazed by the lack of support from your network. Trying for a week now to get help and your help and advice is pathetic when you eventually answer.

  • UberGeekFanboy Fanboy (@UberGeekFanboy) reported from Belfast, Northern Ireland

    @O2 trying to phone through to return a phone and keep getting cut off? Wtf.

  • kkanecelt kierankane (@kkanecelt) reported from Belfast, Northern Ireland

  • catherine271076 Catherine Dwyer (@catherine271076) reported from Jordanstown, Northern Ireland

    @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.

  • salexander835 Stuart A (@salexander835) reported from Holywood, Northern Ireland

  • LouD1991 Louise Dearlove (@LouD1991) reported

    @O2 need to do something about their disgraceful customer service! Long standing customers and get treated like this

  • Hpsaucy515 Helen Peers (was Partridge) (@Hpsaucy515) reported

    @O2 I’m actually with @virginmedia mobile but since they joined with you our data service is rubbish.. we used to use data more than WiFi as that was how good it was.. but not anymore x

  • slowdownpodcast Vinny @ The R&B Slowdown (@slowdownpodcast) reported

    @O2 can I get some help with my phone? Coverage has gone. Can’t make a call to you and can’t receive a text to web chat on myo2 to activate it.

  • Mminimen Margaret💞 (@Mminimen) reported

    @MPD_Online @O2 Clearly not that sorry….. 12 days is far from acceptable for any connection to a network & especially with no definitive as to WHEN connection will happen very poor service!!

  • cortexrock Mark Roberts (@cortexrock) reported

    @UKPowerNetworks can you confirm sending a msg to 80876 is not a chargeable service? @O2 seem to think it is a premium SMS, which I wasn't aware of, & isn't on your promo posts. A mistake? Many people probably sent £££ texts in the last few days. #StormEunice #StormFranklin

  • LouD1991 Louise Dearlove (@LouD1991) reported

    @jsgilbertwriter @O2 The customer service is shocking from such a large company. They lie to you to make the most money possible. It’s rediculous!

  • JuicyGameReview TheGebs24 👉 #Team24 (@JuicyGameReview) reported

    @O2 Since upgrading to an iPhone 13 Pro my data coverage has been ****!! Absolutely ****!

  • bawstobrexit BawstaeBrexit #JohnsonOut (@bawstobrexit) reported

    ******* @O2 a 10%+ rise in mobile phone contracts from April .... You're taking the complete piss 😡😡😡😡😡

  • LouD1991 Louise Dearlove (@LouD1991) reported

    @nataliemolson @O2 Because they are con artists that refuse to sort their problems out. False promises and lies. Especially to their long standing customers. Good luck with getting it sorted

  • KathiaMUA Through Kat's Eyes (@KathiaMUA) reported

    Seriously, as much as I like @O2 for #Priority it has one of the worst 4G signals ever! Don't think mine has ever worked straight off!
