    Really bad service from @O2, having calls from a shop to pressure into upgrades, no really clarity when calling 202 to ask what’s going on-I think I need a new network!

    @O2 not sure when your call centre in Cape Town opened but it’s been extremely painful trying to solve a simple issue..I might of been unlucky but think staff could do with some further training

  • dramattyhealy 🌜cobie🌛 (@dramattyhealy) reported from London Colney, England

    @O2 Hi, it’s been 2 weeks since i started receiving non stop calls from your call centres to get me get a plan with you, the caller said that i entered some kind of contest or signed up for this but i never did since i am happy with my current provider. This is very inconvenient

  • CraigFamilyBlog Hayley & Gavin (@CraigFamilyBlog) reported from St Albans, England

    Gav and I have had no mobile phone service for 3 days, but I have no service to call @virginmedia to let them know! It happens far too regularly. Just spent the morning searching for a new deal. @O2 looks like the best so far!

Latest outage, problems and issue reports in social media:

  • jobiefield jo (@jobiefield) reported

    @O2 customer for over 20 years with 3 phones. Never missed a payment. No credit issues. Trying to renew but they want to know my salary. If I don’t provide, computer says “no”. No wonder customer service level is only 2.3!

  • PabloRocket666 Pablo666 (@PabloRocket666) reported

    @O2 You have ruined Myo2 app completely! Can’t even view my account details. Keeps asking to verify something hundreds of time and gets me nowhere. It’s time to find a mobile network that cares about their customers. Bye o2

  • Anthony07244425 Antlad (@Anthony07244425) reported

    @richecc1 @O2_rep5 @O2 I dread to think how many customers they've lost since the merger, I've had the same issues.

  • icegem44 Icegem 💕🧜‍♀️ (@icegem44) reported

    @O2 your Priority presale for D12 still isn't working on @TicketmasterUK can someone help please? It's not worked at all and I've been checking since 10am

  • mrguddah mr guddah (@mrguddah) reported

    @O2 @richecc1 You know why they and hundreds of your customers are leaving..you do want me to spill your ***** laundry in public? The only going well for is your outstanding customer service..THATS IT

  • anniejowett_77 Annie (@anniejowett_77) reported

    @O2 6 days later this is still ongoing. The mast near my area is not working apparently. What are you doing to fix this? Not only that but my virgin media internet has also stopped working due to an ‘outage’. Last night, my phone was unusable. God forbid there was a family emergency

  • Transome77 Terry Ransome (@Transome77) reported

    @O2 No unfortunately same problem occurs, can’t do anything unless I have my granddaughter with me. And to be honest it’s too little too late! Added to which there was an attempt to scam me following this tweet

  • richecc1 Me (@richecc1) reported

    @O2 Customer 30yrs + you don’t look after customers anymore and coverage seams to be getting worse. Since you merged with virgin your level of service has gone down, typical call to you 40mins for a simple thing and the language barrier just makes it worst.

  • wayner75 Wayne Chant (@wayner75) reported

    @richecc1 @O2 Probably no signal and no 4/5g and phone is nigh on useless

  • RucksSake For Rucks Sake (@RucksSake) reported

    @EnglandRugby @O2 If I talk I get in trouble
