  • JulianLittle4Ag Julian Little (@JulianLittle4Ag) reported from Little Dunmow, England

    Apologies to anyone who has tried to call me at the back end of this week. Badly let down by the useless service @O2 who are now saying that it will take ANOTHER 3 working days to move my number 🤬.

  • SimonHemmingshj Simon Hemmings (@SimonHemmingshj) reported from Chelmsford, England

    @O2 @GarethTurpin I appreciate your personal message. However, I now remember why I left you last time, lower than average service, and now a 17.3% total price increase, which is disproportionate and completely knobbish if you ask me. @BBCNews

  • KevinRowley4 Kevin Rowley (@KevinRowley4) reported from Maldon, England

    @O2 for weeks now, Maldon CM96JR no 4 or 5G signal, voice calls virtually impossible at times. What's going on? Thank you

  • ashley_leggett Ashley Leggett (@ashley_leggett) reported from Great Leighs, England

    @O2 The fact it’s in 3 seperate locations, where my current projects are located, suggests it’s on your side. To use the excuse that there is too much traffic is also ridiculous as means you have over sold your network.

  • LongshanksE10 Richard Astley (@LongshanksE10) reported from Bishop's Stortford, England

    @o2 I ,along with seemingly many others, wish to know why your 4G has been virtually useless over the last week or so please, or better yet, when the service will improve, but you don’t seem to be replying to anyone. Please help.

  • KJDalby Kate Dalby (@KJDalby) reported from Chelmsford, England

    @O2 urgent my new provider activated the PAC code provided by you. Their sim card does not work because apparently my device is locked with you. I cannot text you to get it unlocked. Please help asap.

  • paulhayward200 Paul (@paulhayward200) reported from Wendens Ambo, England

    @O2 Took out a new IPhone contract back in November. No problems paying but I wanted to add a Apple Watch on the account. O2 keep on cancelling the order even though I pass the credit check.

  • chris_rugs Chris Ruggles (@chris_rugs) reported from Great Yeldham, England

    Hi @O2, just a heads up...me and thousands of others will leave your network if you advertise on GB news. Have a long hard think about what you will be funding. #DontFundGBNews

  • JamesSharp87 James Sharp (@JamesSharp87) reported from Witham, England

    Hello @O2 I’ve accidental damage to the rear of my iPhone 11 Pro Max. Only had the phone 3 months so will it be covered under warranty?

  • RyanSchaverien Ryan_Schaverien (@RyanSchaverien) reported from Chelmsford, England

    @O2 Extremely slow data coverage for the past 3 weeks.... any help?

  • 1011FOXEE beverley fox (@1011FOXEE) reported from Takeley, England

    @O2 I am trying to apply the discount I get for working at Tesco,it won’t let me use my email as used for my daughters account,help!!

  • AbbeygaleRose 𝐀𝐛𝐛𝐞𝐲𝐠𝐚𝐥𝐞 (@AbbeygaleRose) reported from Chelmsford, England

    Beginning to regret renewing my contract with O2, their coverage in Chelmsford is awful. My 4G works about 20% of the time. @O2

  • jill_jtc Jill T food safety (@jill_jtc) reported from Sawbridgeworth, England

    @GlassBeadsLotti @O2 Thanks - trouble is it’s not a fault with the phone; service providers have got to up theirs game to stop this happening!!

  • jill_jtc Jill T food safety (@jill_jtc) reported from Sawbridgeworth, England

    @O2 Sounds easy doesn’t it!! Every call is from a different number, it wears me down, in excess of 20 yesterday all blocked & inadvertently called a couple back in error trying to block late at night with brain fog. So cross!!

  • hadhamlane Andy Lane (@hadhamlane) reported from Bishop's Stortford, England

    @O2 ...and then when you’re signed up they change your deal to make you worse off. #O2 reducing the friends & family discount for a loyal customer is the last straw for me.. #O2

  • EmRosePull Emmss (@EmRosePull) reported from Chelmsford, England

    @O2 GREAT NETWORK IS DOWN AGAIN!!
