    @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 😡

  • 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?

  • 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?

    @tescomobile Il try that Jade, but as I said there is lots of people I know with the same issues. Can’t be everyone’s hardware.

  • QuinnKaz Karen Quinn (@QuinnKaz) reported

    @tescomobile there seems to be a network outage, all day yesterday and today too. Can you confirm this please?

  • izzyjo Izzy Johnson (@izzyjo) reported

    @tescomobile continues to be one of the worst companies I've ever dealt with. Having failed to provide me with phone service for almost 2 months, they now tell me I have to pay £184 to leave my contract and go elsewhere. Furious is an understatement.

  • LeilaHenry1 Leila Henry (@LeilaHenry1) reported

    @CeriVW @tescomobile I have had the same problem for 2 weeks.Customer service finally admitted number of customers have been disconnected being migrated from 1 system to another.They cant give a timescale for a fix. Ive escalated complaint to ombudsman so I can change network.

  • jakeyllew06 kath. (@jakeyllew06) reported

    @tescomobile i haven't been able to use my phone unless I am near wifi for 2 weeks. Was told there is an issue with local mast (son on same network no issues) was then told I have to ring you when my phone works properly again to have an account credit 🤔🤔

  • FunkToonEire TinosToonArmyÉire (@FunkToonEire) reported

    @Peakhillfarm @tescomobile Iv to get into my wheelchair to go sit outside to get a signal and they laughed at me so they won't care about your sick Mother sorry to say ,comreg to complain they are not fit for purpose redress is the only way

  • Colin39805896 Colin (@Colin39805896) reported

    @erictheaardvark @tescomobile I'm having the same problem.

  • thurlow_amanda Amanda Thurlow (@thurlow_amanda) reported

    @tescomobile Liz the rudeness was the abruptness of “that’s it we can’t tell you anymore so that’s just tough” or that’s how it felt. After a month of being fobbed off I now can’t phone out on either phone & no one can help me! It’s beyond frustrating & given I wouldn’t choose Tesco again!

  • beardylonghair Mike Johnson (@beardylonghair) reported

    @tescomobile Your helpline number advises people to use the online chat function as the quickest way to contact you, but the web chat function on your website is broken. How exactly am I supposed to contact you?

  • FunkToonEire TinosToonArmyÉire (@FunkToonEire) reported

    @Peakhillfarm @tescomobile @eir 10 euro month for a much better service customer care who dont ask illegal questions
