    @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.

  • GeorgeCowan Britishgamerni 🇬🇧🏳️‍🌈 (@GeorgeCowan) reported from Whitehead, Northern Ireland

    @Jewkneeor @O2 @VodafoneUK Honestly terrible service here I think it’ll be EE or 3 from the look of it when I go to change provider at the end of my contract

  • GeorgeCowan Britishgamerni 🇬🇧🏳️‍🌈 (@GeorgeCowan) reported from Newtownards, Northern Ireland

    @O2 Yeah that doesn’t give any way to report an issue or anything not helpful

  • McGuinnessKevin Kevin McGuinness (@McGuinnessKevin) reported from Belfast, Northern Ireland

    @o2 any chance you can sort out the masts in Belfast.. really slow connections and dropped connections, I’m even with o2 (was with you when it was BT Cellnet) I’m with sky who use your network but I know of o2 customers having the same issues. #o2network

  • TheRealJackieJ Jackie Johnston (@TheRealJackieJ) reported from Castlereagh, Northern Ireland

    @O2 Thanks. How do we unsubscribe from this ****? We pay for 5 contracts and do not wish to receive these messages particularly on children’s phones.

  • SimplytheTess Tessa Dowling (@SimplytheTess) reported from Croydon, England

    @O2 nice that someone has taken a phone and contract out in my elderly, disabled mother's name and O2 wont help us out at all because she can't give you the password or security answer. Of course she can't, she didnt open the account! Can't even cancel the account, or 1/2

  • usmanyounas0011 Usman Younas (@usmanyounas0011) reported from Walthamstow, England

    @HowardGriffiths @O2 and if you are on call your call will be dropped(call failed)then it will take sometime fr service to start working again.. 2ndly most of the places getting only 1bar and very slow data browsing.. 3rdly when it connects to 3G it’s same like No Service it goes sooooooo slow 2/2

  • grannypatt Pat Waistnidge (@grannypatt) reported from Sheffield, England

    Such tempting offers from @BTGroup for mobile service. As we have all other @bt_uk stuff may give them a try. Been with @O2 for years no problems but no incentive to stay when contract up next month. #dontbitchswitch

  • huwbevan huw bevan (@huwbevan) reported from City and County of Swansea, Wales

    @O2 really bad customer service from O2 today. One part of the company not listening to another.
