  • PaulWRamsay #HellomynameisPaul (@PaulWRamsay) reported from London Colney, England

    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!

  • sarahcoysgabb sarah gabb (@sarahcoysgabb) reported from Broxbourne District, England

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

  • AddictiveColors Addictive Colors (@AddictiveColors) reported from London Colney, England

    @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

  • jodyrandall Jody Randall Esq. (@jodyrandall) reported from Broxbourne District, England

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

  • AFCAMDEN AFCAMDEN (@AFCAMDEN) reported from London Colney, England

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

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @O2 just to say that I have received a replacement phone which is a positive, however I hope they take this example of my frustration with their Customer Service in to consideration and keep their valued customer updated

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

  • stourdave Dave (@stourdave) reported from London Colney, England

    @O2 How did this shit happen

  • 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

  • shirleyjennerUK Shirley Jenner (@shirleyjennerUK) reported

    Just been waiting for over 1.5 hrs to get though to O2 customer service @O2

  • shearn1986 Shawn Hearn (@shearn1986) reported

    Quite sad that you contact @O2 about network issues and how it doesn’t reflect their coverage map at all and their answer is simply “tough” all of our #Bracknell masts are all out of service indefinitely for upgrades that may or may not be happening.

  • woolenhattwitch woolenhat (@woolenhattwitch) reported

    How long are you planning on fixing the mast @O2 I've been without service for ever and I have **** to do!!! 👿👿

  • QuantumSkyline Quantum Skyline (@QuantumSkyline) reported

    @SteezeMcQueen1 @O2 I lose data signal at least 5 times a day. Coverage is awful

  • NicolaL01 NickieJ (@NicolaL01) reported

    @O2 I want £32.00 per month in total over 24 months, why are there offers to new customers?, why when I try to upgrade online I get higher costs, I'm about to move to 3, I've had no phone signal for 5 months, only credited back 2 months, retention of customers mean nothing to you

  • MadCatMyrtle Mad Cat Myrtle (@MadCatMyrtle) reported

    I’ve been with @O2 forever. I upgraded yesterday, and like every other time, staff in the shop couldn’t do enough for you when selling! When done, they don’t want to know you, and look at you like you’re a P.O.S**t. Customer skills.. zero. 14 days to change my mind .

  • xgemm_x Gem✨🦋 (@xgemm_x) reported

    @djcue1986 @O2 Honest it’s a joke! Been with them for years as well no issues. Tried speaking to them last week and got no where, apple weren’t much help either though😩

  • DawnOfLight Jack Cartwright (@DawnOfLight) reported

    Switching to @O2 from @EE has to be the worst choice I've made. Worst Internet connection I've ever had and I can Barley be heard on any calls.

  • psyske ske (@psyske) reported

    @O2 please fix CH2 1BQ (@TheCountessNHS site) signal is woeful

  • shannon87457923 shannon (@shannon87457923) reported

    @O2 Using an iPhone 11 only calls work. No texts or data working. Happened in Portugal few weeks ago too. Tried manually resetting network didn’t work either
