    @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.

  • Watsonmydear Christine #StaySafe #SaveLives Watson 💙 (@Watsonmydear) reported from Belfast, Northern Ireland

    💡 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

    @seanp280 @O2 Where are you in Belfast? I live beside city hospital and I get full bars all over the city, 5G too! Only when I venture into the depths of County Down does it deteriorate lol

    @Girlzmum Very poor service from @O2 especially to a front line worker in the NHS #NHS who needs her phone.

  • 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.

  • 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.

    @sumlin @O2 O2 are up there as one of the worst customer experiences of all time, switched to giffgaff 10 years ago for 30gig at that price and a friendly text letting me know if I’m using enough to justify that monthly package

  • Sentfromdevon1 Sentfromdevon (@Sentfromdevon1) reported

    @O2 this number keeps harassing me claiming to be O2 service centre. I've told them I am not interested in what they are selling, because i believe it's a scam can you check and see if this is your number 03701020201

  • tizannabeth Tizzie (@tizannabeth) reported

    I paid my @disneyplus subscription with my @O2 phone bill. I’ve now left O2, but I can’t change my subscription details on Disneyplus without using my O2 account which I can’t access. Help?

  • AmarAkhtar Amar (@AmarAkhtar) reported

    @O2 hi I have new Samsung watch 4, 4G and cannot make calls if phone is off + calls go to VM instead of the watch. Surely this can't be because the only plan you have is data only and has no minutes and txt? Was told you will cancel the plan as there is nothing else you can do?

  • aah9713 Aniqa (@aah9713) reported

    My identity was used to take out contracts with telecom companies Three, Vodafone and Carphone Warehouse - ALL resolved the issue within a few weeks whereas I have been chasing @O2 for 3 months with no updates or progress!! #fraud #identitytheft
