  • 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

    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?

  • 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?

  • 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

  • VinnieLouu Katie (@VinnieLouu) reported

    @tescomobile @gerryculbert1 Don’t even believe their lies!!! 3 weeks later, and I’m still without signal and I’ve heard all the excuses under the sun. And conveniently I’ve dealt with “Liz” EVERY SINGLE EXCUSE.

  • KevinGibbins1 Kevin Gibbins (@KevinGibbins1) reported

    @Craigo71 @tescomobile @O2 New phone, 100Gb of data for £20 a month, 24 month contract, with 3. A couple of minor technical issues (mainly because I'm technically inept) which were sorted really quickly. Decent signal coverage. I was with Tesco but they couldn't match that.

  • Jaibxxx Jamie bonner (@Jaibxxx) reported

    @tescomobile manager was supposed to call me back at 630 after her 2 hour lunch to discuss a member of staff mimicking me while she thought I was on hold … still not been called what shocking customer service

  • Flossrules Louise Hill (@Flossrules) reported

    @tescomobile help! I get no internet when off Wi-Fi (I have 100GB no not a data issue) if I turn off/on it comes back but then drops again! I can’t keep repeating. Driving me mad 😡

  • Chriscurson Chris Curson (@Chriscurson) reported

    @tescomobile Hi Sean. everywhere and since I moved my phone to Tesco. I have had a new phone and new sim and the problem is still there.

  • gez_666 gez howarth (@gez_666) reported

    @tescomobile Been in again today, same result technical problems

  • RossandLucinda The L. (@RossandLucinda) reported

    @tescomobile Could someone help direct me to a person who can over ride the system so I can buy the phone today and put this stress behind me as its been going on for 10 days and im going round in circles in store and on phone because no one is qualified to know what to do. My bank are fine.

  • PeterIbitoye2 Peter Ibitoye (@PeterIbitoye2) reported

    @tescomobile why is my roaming not working in Portugal

  • Jaibxxx Jamie bonner (@Jaibxxx) reported

    @tescomobile wow never experience such bad CS. I rung to query my bill, 1st caller line cut out she didn’t call back, I called back she hasn’t even left notes. 2nd lady thought she put me on hold while I listened to her whole convo of her mimicking me to her colleagues!!

  • JRAnalytics__ JR Analytics (@JRAnalytics__) reported

    @tescomobile absolutely astounded at the horrific service we’ve received. Returned our contract within 14 days as you don’t offer WiFi Calling. Returned the device in the same condition we purchased it in and today you’ve taken £600 out of my account and I cannot pay my rent
