    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

    @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

  • 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 😡

  • Saffi_f1 Saffi 💙 (@Saffi_f1) reported

    @tescomobile I would like to add that I have very recently joined you from another network and kept my number and have just read a tweet from someone else that this is a known fault?

  • Helen1971 Helen Williams (@Helen1971) reported

    @tescomobile @WhichUK But yet I have had no data in June and just get it’ll be fixed “soon”! Appalling service

  • Mysterybeatzuk Marc (@Mysterybeatzuk) reported

    @BaileyIntabeats @VodafoneUK Only half as bad as @tescomobile trust me! So don't switch to them 👌

  • DragonWolf5589 Jay Smith (Sonic/Dragonwolf) (@DragonWolf5589) reported

    @O2 @tescomobile me and a friend is on tesco mobile and 2 other friends on O2. We all keep having issues with our texts not sending which yesterday an important one didn't come through. Is there any issues across the entire network or whole of manchester as we all have issues

  • GregorThomas2 Gregor Thomas (@GregorThomas2) reported

    @tescomobile @WhichUK Shocking considering I am unable to use mobile data. So effectively paying loads just for calls and texts. Not good service

  • Saffi_f1 Saffi 💙 (@Saffi_f1) reported

    @tescomobile Hi. I'm having trouble staying connected to mobile data. The only way to get it back is to restart the phone. Then it will only last for a couple of hours then drop out. Thanks

  • theboydonald Theboydonald (@theboydonald) reported

    @tescomobile PAC code done almost 2 weeks ago, 5 times on the helpline and still no data. “Ongoing issue with a number of transfers.” Told Wed it would be sorted by Friday, another lie.Contract started 18/5 and problems 14/6 which is apparently over my 30 days 🤔

  • theboydonald Theboydonald (@theboydonald) reported

    @tescomobile @WhichUK Yeah right! Any of us wondering when we might get mobile data due to “ongoing issues” with our PAC code transfers ( 2 weeks, 5 calls,2 hours) might disagree.

  • AlexBonsss Alex B (@AlexBonsss) reported

    @tescomobile dog **** you are, never ever get any signal!
