O2 Outage in Knebworth, Hertfordshire, England

@O2 Is incoming calls down as I have had so many missed calls from people who have had to call on landline not good for business

@O2 trying to upgrade on app and main website but when I choose it crashes can anyone help

@O2 sort your cancellation team and phone problem out. #poorcustomerservice

@SkyNewsBreak Would cancel my contract with @O2 immediately if they did.

@O2 I understand that carriages speed and materials do not help, but repeaters in tunnels sure would to avoid disruptions especially as they can particularly nasty to a laptop when the phone or the train is the hotspot as that side of the connection never goes down just the gateway’s

@BBCNews @O2 worst coverage ever no solutions. The network towers always down but yet I'm still paying 55£ p.m i have no choice but to pay!! #ripoffbritain #conmen

@O2 why is your 4G so bloody awful at Liverpool Street Station

@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

@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

@O2 @tescomobile No mobile signal in Great Ashby, Stevenage all day!!

@O2 are gonna have to either offer me an amazing deal or sort out this horrendous signal issue. How can I not load a twitter video when I have a full 4 bars of 4G signal

@O2 I'm sick to death of your network. I'm trying to pay you and I can't. Now I'll wait for some fool to contact me. I give up with this pathetic network.

@O2 How did this shit happen

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!

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!

@EmmaShubrook @O2 Agreed. I have no signal at all

@O2 I do have the app, I think I will phone the customer service team and ask them,

@VModifiedMind @benwood @EE @VodafoneUK @ThreeUK @O2 Albeit using half rate codec for voice. Sounded pretty awful.

@O2 Well it’s every time I leave Leicester. Or go to a new city.. even when I have 4 bars it’s either really slow or won’t load at all!

@O2 what is going on! 😭😭 Even when I have signal it's so slow!

@O2 have said I can have £10 back because I am a loyal customer Thanks that’s £40 for a phone that doesn’t work 🙌🏼 But if I don’t pay my bill I get a bad credit score

@O2 I have been a customer of yours for nearly 10 years now but I will be leaving you as soon as my current contract is up as you are one of those companies who don't reward loyalty just new customers.

@O2 £50 a month on a phone contract that is useless Signal doesn’t work without WiFi 12 months it’s been like this and just get told it will get better Family on @VodafoneUK don’t have this issue

@planetcallum @ThreeUKSupport @ThreeUK @O2 Interesting that @ThreeUKSupport continue to refer to Payforit, which ceased to exist in December 2019. These charges are clearly the result of a contractual relationship between @ThreeUK and ModoMobi, as evidenced by the fact that the scam only operates on the Three network.

@O2 wow never experienced such bad customer service. Spoke to 4 different people who were all unable to help reduce my bill, the 4th of which just hung up on me mid sentence. O2 are clearly not willing to help people who #badservice #CustomerService #phone #financialhardship

Day 11 & the @PSAuthorityUK still unable to answer. I suspect it’s because they either really don’t have a clue, or there would be retrospective legal action from previous cases. Can you help please @Ofcom @aimmtweets @commsadruk @ThreeUK @O2 @EE @bt_uk @VodafoneUK

@Ben_zilla @O2 I’m having the same problem in the WS1 area

@O2 losing signal on walsall area

Wow @O2 need to update their customer service hold music😅

@ThreeUKSupport I just want to leave. Your service is crap. Signal is crap. Big mistake moving from @O2 to you.
