    Anyone else on @O2 find their app never works.

  • Xynthymr Xynthymr (@Xynthymr) reported

    I've been an @O2 customer for over 20 years, but these latest mid-contract price hikes are unsustainable. Only reason I even have a SIM is because of 2FA, otherwise I would go SIM-free Wi-Fi only. I'll probably be switching to @giffgaff or @LebaraMobileUK soon. Well done, #O2!

  • danfelton Dan (@danfelton) reported

    @O2 worst network ever. As soon as my contract is finished, I am done with you. Awful awful network.

  • SimonMoorcroft Simon (@SimonMoorcroft) reported

    @O2 is either having technical issues or the website is currently under attack. Is this linked to the 40% increase @MartinSLewis @Ofcom

  • qlexroby qlexroby (@qlexroby) reported

    @O2 what’s going on with my data you *****. 5G 4 bars but doesn’t work sometimes? Then you have the cheek to send me an email about prices increasing. **** you. *****

  • Xynthymr Xynthymr (@Xynthymr) reported

    @MartinSLewis These price hikes are disgusting. How is #OFCOM even allowing this!? I've gone from having a sub-£9/mo @O2 SIM to it being nearly £15/mo in just the last 24 months! For something I very rarely use, but require because of 2FA reasons 🙄 20+ year customer. Not for much longer! #O2

  • wmpben Ben (@wmpben) reported

    Hello @O2 quick question, how, after being a customer for 22 years am I hearing about mid-contract price hikes from @MartinSLewis before you?

  • fozzer007 Andrew Forster (Fozzer) Adidas Addict (@fozzer007) reported

    Wow @O2 — weeks of a broken voicemail and not one person who can fix it. Every agent repeats “try 1750/1760.” Still broken. Your customer care is honestly awful — no ownership, no escalation, no help. Loyal customers deserve far better. #O2 #CustomerServiceFail

  • dog_gem Adrian (@dog_gem) reported

    So @O2 have decided they will be increasing airtime plans by £2.50 from April 2026 instead of £1.80 What is the justification for this larger increase, and what will customers see in terms of benefits/better service, or is this just to keep shareholder profits nice and high

  • HughesDigital Kevin Hughes 🎥 (@HughesDigital) reported

    @Ofcom The only scams are when companies like @O2 put their prices up mid-contract. How about clamping down on that @Ofcom? You are not fit for purpose, I feel internet and mobile companies are scamming consumers every April and you do nothing to protect us from these unnecessary hikes
