    @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

    @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.

  • 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.

  • IanRobinson Ian Robinson (@IanRobinson) reported from Stormont, Northern Ireland

    @chriswb @O2 No. Plus it says No Service where the O2 logo should be. I might try the SIM in my O2 iPhone.

    @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.

  • JamesRoberts330 James Roberts (@JamesRoberts330) reported

    Hey @O2 how long is it normally between a new mast being erected and it being turned on and active? There’s a new mast gone up by my house (after Feb 2022) showing that it’s 5G but there’s no 5G in my area on the coverage map so it’s still not working yet. Thanks. James #O2 #O2UK

  • 01mvhd wealth & riches❤️❤️🕊️ (@01mvhd) reported

    @LewisBeechey @O2 Talk to @iFox97 they helped me when support services wouldn’t help me🥺..

  • Kayoprice3 Kayoprice (@Kayoprice3) reported

    @O2 After all, my phone never been connected to mobile network in Spain. It was a terrible experience. What is the reason do you think? I don’t want the same thing happen again!

  • MissFlanagan22 Miss.Flanagan (@MissFlanagan22) reported

    @O2 I can never get through to the online conversations? Every time it says that you’re currently too busy right now. No matter what time I try. I need to speak with someone regarding the service where I live, it’s an ongoing problem and I’m starting to get really frustrated

  • chelsea_woodss Chelsea Woods (@chelsea_woodss) reported

    Honestly think 02 has the worst customer service team I’ve ever dealt with. Trying to deal with such a small issue over the phone turns into a 2 hour call getting passed around to over 12 people….and then they hang up!! Lord give me strength, glad I’m changing over @o2 @TheO2

  • MarysiaT Marysia Trembecka (@MarysiaT) reported

    @O2 2/2 Vodafone are saying they cant access it as port is done in full, no issues their end. o2 are saying they waiting on vodafone - they emailed 16/2 - I am stuck in the middle now with no text msgs for 4 days.. and no way to verify bank statements, chrome and apps such as uber.

  • Ste_wheels Stephen tyler (@Ste_wheels) reported

    @O2 why is your signal soo poor in Birmingham. Lucky to get signal in 5% of it!!

  • GaryElsey Gary Elsey 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@GaryElsey) reported

    @O2 after 4 months and much fobbing off, the phone signal in my house is still a joke. Have to go a mile away before someone can hear me speak. Sort the masts out in Swansea SA4 region. Was working perfectly until you made changes

  • msubani__ CHI. (@msubani__) reported

    @O2 a disgrace. 7 complaints on file. 2 tickets raised. and STILL nothing. since I l landed on the 9th January I have been going back and forth with your advisers and still no progress? as a company are not ashamed that your customer service is truly some BS?

  • LJB150192 Luke Baker (@LJB150192) reported

    @O2 Never in my life experienced such shocking customer service as I have with o2. On-going complaint that hasn't been resolved in over 4 months. Continually told that a manager will call me back within 24 hours but no one ever does. Worst provider imaginable!
