  • ShanWilson_ Shan Wilson (@ShanWilson_) reported from Hemel Hempstead, England

    @O2 @mtsavor I cannot call 202 or any other number that is supposed to be “o2” as I don’t know who I’m talking to. I’ve been hung up on twice when I’m explaining what’s happened. I need to cancel the iPhone contract or change the address with an actual o2 staff member!

  • ian_slade2 Ian Slade (@ian_slade2) reported from London Colney, England

    @O2 is the data network down? Zero mobile data connectivity all day. Plenty left on the plan

  • JoshBates Josh (@JoshBates) reported from London Colney, England

  • misswotless1 Miss Wotless (@misswotless1) reported from London Colney, England

    Remind me never to frequent the @O2 store on Oxford Street again - so rude and unhelpful, telling the customer before me not to come back

  • Palouisea UnhappyHoopla (@Palouisea) reported from Shenley, England

    @VOXI_UK I have been on a staycation this week I am appalled at how poor your reception is in many parts of South East. Going back to @O2 as sim only!! Very frustrating 😕 missed many important phone calls. Pm me to discuss

    @O2 @Joegreaney Hi I'd just like to add that this is a problem for everyone on 02 and giffgaff in that area and it's because a mast in hither green has been down for 2 years and these crooks hate you enough to ignore it.

  • EmJen81 Matthew J (@EmJen81) reported from Dunstable, England

    @O2 Why, for the past 6 months can I STILL not upgrade my phone online or any of your stores due to your dire lack of stock. I've had this phone for 3 years and it's dying. Yet you never seem to have any stock. Other networks aren't having issues!? Time to switch perhaps.

  • ChristianRad Christian Radnedge (@ChristianRad) reported from London, England

    Something especially egregious about living near The O2, but not having any @O2 signal once again, even though that doesn't make sense. Feels like it should be a massive router for all of South East London...

    Switched to @O2 from Vodafone. Live chat seems to default to saying everyone busy and calling customer services I just got randomly disconnected 🙄

  • MainPietra pietra main (@MainPietra) reported

    @O2 Hi 02, its been a week now and still no phone after have put in a claim. I need to travel. You shold give me another Samsung if this is out of stock. Appalling! O2 are very good at taking my money though!! I want to cancel my contract with yo after 17yrs!

  • PeadarRea Peter Rea (@PeadarRea) reported

    @O2 I cancelled a new phone contract on 27/7. Still appearing on my account & money still being taken. Customer services so unhelpful. 3 people spoken to so far and 2+ weeks later still not resolved. Appalling customer service. Been with O2 for 15years. No longer.

  • stupot74 Stuart Kerr (@stupot74) reported from Overcombe, England

    @O2 Why don't you care about your customers o2??? is it company policy to just ignore anyone with a genuine grievance? are all your customer service representatives trainees?

  • ixlxnx12 🦀 (@ixlxnx12) reported

  • normafoulds Norma Foulds (@normafoulds) reported

    If you are thinking of getting a new phone provider don’t go with O2 , worst customer service I have had for a very long time #o2worstcustomerservice #phone @O2

  • holtyg Guy (@holtyg) reported

    @SamsungUK @A1CommsLtd @O2 Cannot begin to describe how exhausted I am trying to deal with the poor customer service provided by these three companies. All in relation to a simple phone and network contract order. From lies to incompetence. Lots of apologies but nothing changes.

  • JoshHarris91 Josh Harris (@JoshHarris91) reported

    @LeytherMatt @WhiteArmy90 Everytime I go anywhere near the Reebok even just to Middlebrook or to the DW stadium I have no phone signal on @O2 they have said it’s due to signal congestion but that is just a crap excuse.
