    @tescomobile Hi, can you tell me if Tesco intends to support Apple Watches any time soon on a cellular level. If not why? O2 network is used on Tesco mobile…. How far apart can an iPhone be away from a watch if used and will your Apple Watch connect to all available WiFi?

  • nigelbendybus Nigel Smith (@nigelbendybus) reported from Cardiff, Wales

    Thank you so much @tescomobile for sorting out and reimbursing me for the scam texts I received yesterday. Yet again wonderful customer service from @tescomobile

  • soozles_ Soozles (@soozles_) reported from Barry, Wales

    Seriously getting sick of the awful signal from @tescomobile 4 years I’ve been a customer and have 4 contracts with you spending &150-£160 a month and it’s getting worse everyday! Been trying to speak to someone all day (friend) and constantly getting call failed 😡

  • soozles_ Soozles 🏴󠁧󠁢󠁷󠁬󠁳󠁿💙 (@soozles_) reported from Barry, Wales

    @tescomobile I can’t call or receive calls today, get call fail on them all but I’m able to text and use data without a problem. Is there a problem in the CF63 area?

  • HAndTheElements Hegsy & The Elements (@HAndTheElements) reported from Cardiff, Wales

    @tescomobile what is the escalation process regarding a faulty phone that has been lost by @Tesco? My OAP mother has been without a phone since September and promises to resolve have failed. No senior support from Pengam Green Management or in-store guidance. #disgracefulservice

    @bocajjj1 @tescomobile Hey, the living wage is £9.90 per hour, which Tesco have refused to pay their customer assistants. So no, I'm not :)

  • arw84 Adam Whiteley (@arw84) reported

    @tescomobile Same as you do at the petrol pump. Yet you struggle to drop the price when the costs go down.

  • MelissaCroucher Mel (@MelissaCroucher) reported

    @tescomobile I am now on day 4 of not connecting to 4G, only a very slow 3G, I pay ridiculous amount a month I expect to be connected to 4G, unable to go into a store due to work, what do you suggest? I’ve tried restarted phone etc. And I work all over London so not area specific

  • JohnNLondon1 John N London (@JohnNLondon1) reported

    @tescomobile @Djaievd I really don’t care if you adhere to the CAP code, my daughter took one look at the “Shiit” and declared “that’s rude!”. Reported.

  • LightescapeEve Lightescape Events (@LightescapeEve) reported

    @tescomobile But you leech off of the o2 network don’t you? That can only mean 1 thing. You have no doubt applied the same pressure you apply to fruit & veg growers for reduced prices. Not really an ethical thing to do to b!tch about other suppliers when you are screwing them over is it?

  • Poolster David Poole (@Poolster) reported

    @tescomobile Tesco are a PLC so what ******** are you on about?

  • fagankevin Kevin (@fagankevin) reported

    @tescomobile @HaydnAshlee Shocking performance by a supermarket. Will never visit you again. Blocked.

  • Demon_Licks Demon Licks 🔞 (@Demon_Licks) reported

    @tescomobile What a **** take

  • grumpysorrysort John Mason (@grumpysorrysort) reported

    @tescomobile spent hours upgrading to i11, over 24 months. Then get agreement through for 36 months. Then told we do not sign agreement and have to through upgrade again as it cannot be altered. We have done nothing wrong. Bad customer service.

    @tescomobile I find this tweet pretty odd... slating the "big mobile networks" but you use O2 as an MVNO. Sounds like you need a big network to operate? 👀
