@O2UK European roaming is a myth!this deserves national attention. #O2Fail #O2Support #BrokenService #CustomerServiceFail #consumerProtection

@O2 Support experience? A disaster: 📁 Case opened ❌ Then closed, unresolved 📁 Reopened, told “3–7 working days” again ☎️ Promised a call on a backup number — but no one ever tried. #O2Fail #RoamingNightmare

@O2 Meanwhile: 💷 I’m losing £100+ per day due to missed calls and being unreachable 🪙 O2 offered £10 credit 🧩 Shared a complaint line I can’t call (because… the phone doesn’t work) #O2Fail #RoamingNightmare

@O2 anyone know how you cancel a contract with o2? They say to phone but no one answers. 40 mins on hold so far. Is it a con so they can keep taking your money? #o2fail

@O2 Day 12 – Still no resolution from @O2UK No working calls. No updates. No escalation. You left a voicemail I couldn’t receive — then did… nothing. I’ve asked multiple times to be contacted via WhatsApp. Ignored again. This is now just negligence. #O2Fail #O2Support

7/11 Dienstag: Kein Netz! Erneut bei O₂ vorstellig, diesmal mit mehr Ungeduld. In der Zwischenzeit hatte ich Montag und Dienstag zahlreiche Gespräche mit VF, um sicherzustellen, dass meine MAC-Adresse wirklich frei war – und ja, sie war es! @bnetza #o2CanNotDo #O2Fail

@o2cando Weiter geht's, zweiter Brief mit eSim ... Wieder ein falscher Code, bzw. QR Code ohne Inhalt. Enthält nur "LPA:" #servicefail #technikfail #o2fail Wo muss man sich denn melden das man diesen exzellenten Service von Euch bekommt, aktuell kann ich den nicht finden.

6/11 O₂-Mitarbeiter startet Aktivierung und das soll max. 4h dauern. Aber nach 5 h? Genau, immer noch kein Netz. Nochmal Anruf bei O₂: Wo ist mein Netz? Die Antwort: 'Ich erstelle ein Ticket und wir versuchen es erneut.' #o2CanNotDo #InternetOdyssee #O2Fail @telefonica_de

@O2 @vm_o2 @appleuk Please Repost and Share this thread, it’s about false selling and total disregard for customers. Please repost so @O2 @vm_o2 and @AppleUK are held accountable. #O2Fail #CustomerServiceFail #AppleWatch

Honestly can’t believe how @O2 are carrying on. I was a victim of SIM swap fraud, left with no service for nearly 2 weeks, and told all costs would be covered. Now they’ve got the cheek to text me saying I owe £145 this month. An absolute disgrace. #O2Fail #O2Disgrace #O2Fraud

@O2 Shoutout to @O2 for reminding me what life was like before phones. No signal, no support, no idea what's going on. 👏 #O2fail #CustomerService?

Update: I just got a voicemail from @O2UK — but no call ever came through. The message? “We couldn’t reach you, keep your lines open.” That’s the entire issue: 📴 I can’t receive calls. 📞 So why use voicemail instead of fixing it? #O2Fail

Schlechter O₂-Empfang in meiner Wohnung seit Jahren. Sonderkündigung abgelehnt – aber Telekom/Vodafone funktionieren hier perfekt. Nie wieder O₂. #o2fail #o2de

@MarkEvansO2 @O2 #O2Fail After contacting various channels, I still haven't received a proper response. I haven't received any messages on my old number, and this is causing a huge financial impact. Who will bear the cost? Please reply!

Is @O2 the worst network in the UK? Went on a family trip to North Wales—both of us had O2 SIMs. Shockingly poor signal even in central Llandudno. We had a family emergency and O2 completely let us down. Totally unacceptable in 2025. #O2Fail #UKMobile

@O2 😡 SHAMBLES of a company! 😡 Fraud reported on my account on 27th Feb 2023. Today's 20th April and you STILL haven't resolved it! Charging me for a FRAUDULENT transaction! 🤬 #O2Fail #Fraud #TerribleCustomerService

@O2 Absolutely fuming. Over 3 hours wasted with your call centre—no help, no fix, and still stuck with useless signal in Shrewsbury. Loyal customer clearly means nothing. Sort it or I’m gone. #O2Fail #ShrewsburyDeservesBetter

The 'experts' at @o2 took 6 wks to reply to me about an account I couldn't access online. I resolved the issue myself in the end by adding the account in question to my main phone account. Makes me wonder why none of them suggested this. Maybe I'm the expert. #o2Fail

@lebara @O2 your port in teams need to fix this! Told 24 hrs then 48 then 72 then 24 and now another 60 hrs B/C U DON'T WORK W/ENDS🤬- finances, healthcare, business customers all affected. Worst customer service EVER! #SPLITPORT #problem #EpicFail #lebarafail #O2fail
