    💡 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

  • rf_twit Rory (@rf_twit) reported

    Customer of @O2 for more than a decade naively (loyally?) does not check competitors before sorting upgrade and was yesterday promised a call back today (that did not happen). I call you back this evening and am given completely different info to yesterday's info. How so?

  • LaauraAnne laura (@LaauraAnne) reported

    @O2 My signal has been very low on and off and today someone called and it went straight to voice mail. That’s the only issue I’ve had with calls and texts have been fine :)

  • bhesmondhalgh Brian Hesmondhalgh 💙 (@bhesmondhalgh) reported

    @O2 I have been calling your support line and keep getting thrown out. I have a technical query and can’t get an answer. Not a good customer retention scheme.

  • PipelineLand Pipeline Land Access Ltd (@PipelineLand) reported

    @O2 #network #data #**** not sure what I pay £100 a month for?Certainly not the service, hope the home schoolers do better than the paying customers 💩

  • Asif15584925 AV8 (@Asif15584925) reported

    @kellyfhaycock @O2 I’ve been with O2 for 24 years what have they given me NOTHING apart from poor customer service

  • samcott23 Sam Cottingham (@samcott23) reported

    @O2 mobile signal is absolutely shite. Why I changed from @EE I don’t know. Is there a way you can just terminate your contract, hand your current phone in and cut all ties so I can take out a fresh contract with EE? Helppp

  • bigdunzz dan 🥊 (@bigdunzz) reported

    @O2 currently getting no signal or internet, any idea why?

  • flatpacks Simon Earl (@flatpacks) reported

    @O2 If Bubl was available then I’d buy Bubl over a phone as Bubl could solve all the worlds problems !

  • Sanhall74 Suzanne Hall (@Sanhall74) reported

    @O2 Can you advise how I can bypass your absolutely shocking customer service & complaints teams and actually resolve an issue of a non delivered phone? 14 days and losing the will to live!!!

  • JenLipgloss LIPGLOSS💋 (@JenLipgloss) reported

    I’ve ordered a SIM card replacement over 7 days ago and it still hasn’t been delivered. Appalling customer service by @O2 !
