    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 😡

  • 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

  • RachelKendall16 Rachel Kendall (@RachelKendall16) reported from Risca, Wales

    @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?

  • mind4sportpsych Dr Karen Howells (@mind4sportpsych) reported from Cardiff, Wales

    @tescomobile I have not had a signal for 3 days now. I’ve been told that there is maintenance work being done on a local mast, but even when I move 30 mins away from home then I still don’t have a signal. What is happening??

  • Saeed_Ahmed02 Saeed Ahmed (@Saeed_Ahmed02) reported from Victoria, Wales

    @tescomobile needs to better support the Google Messages app. I quite like using the Google Assistant to send texts and it always comes back saying 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?

  • TRHComposer Thomas Richard (@TRHComposer) reported from Cardiff, Wales

    @tescomobile my mobile data has just stopped working. Still got over 10GB available to me though. Is there a Network problem?

  • 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

    @tescomobile I have, repeatedly, it just keps saying phone mast is not woking as it should. 2 days now with no estimated fix time

  • MarkJamesWalton Mark Walton (@MarkJamesWalton) reported

    @SaraSkinner17 @tescomobile I've had great customer service!

  • izzyjo Izzy Johnson (@izzyjo) reported

    @tescomobile It cannot wait more days. 72 hours to wait for a fix is not good enough. How can I escalate this further?

  • ChrisGu43069649 Electric Chris (@ChrisGu43069649) reported

    @tescomobile Tesco mobile con people steal money and treat people like ****

  • EveAinsworth Eve Ainsworth (@EveAinsworth) reported

    @V1SEO @jocotterillbook @tescomobile I will never do one again

  • StephenTaylor70 Stephen Taylor (@StephenTaylor70) reported

    @tescomobile Why is everything 25p dearer for everything in tesco than every other supermarket even with clubcard discount. Youre despicable, using everyone as a cash cow, profiteering during a national crisis on the back of bumper profits during lockdown. Usury of the worst kind

  • alexklaushofer Alex Klaushofer (@alexklaushofer) reported

    @tescomobile Don't like that scheme to reduce prices only for those with a card. Felt I got scammed when I got charged much more than the ticket said at the cash desk. And the close-up surveillance cameras are general atmosphere are horrible. I just don't want to enter the store any more.

  • pickled_tinker Grody🔞 (@pickled_tinker) reported

    @StewMasters @tescomobile They use O2 and O2 has always been a crap show. Thankfully, they are getting much better now thanks to Virgin (gave O2 a shyte load of backhaul capacity).

  • pmb200 Paul Bailey (@pmb200) reported

    @chrisisadolphin @StewMasters @tescomobile I struggle getting data and it's taken 10 weeks for them to offer to cancel the contract if I pay off the phone (option available to me anyway) or 2 months data back. The customer service is excellent but the actual phone service is very poor (in my experience).

  • MufcAnt1975 AntMufc1975 (@MufcAnt1975) reported

    @tescomobile Prices down? Everything I see has gone up
