    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 😡

  • 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

  • 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?

  • 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?

  • 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

    @tescomobile well what happened to customer service the deal I wanted over chat told it’s discontinued.. my response oh no never mind..reply was ok bye Julie end of new phone contract conversation !Errr what about other deals you may have on offer it’s like no one cares anymore

  • dirtylilmonkey Geoff Racle (@dirtylilmonkey) reported

    @clairefweir Just spent an hour talking to one of your overseas "Care" team, sadly she will not earn even a miniscule portion of your salary, but she tried her very best to help me. She didn't ignore me, as you have! TescoMobile require "leadership by example", not ignorance.

  • Carrjohnadam Mr Adam J Carr (@Carrjohnadam) reported

    @tescomobile This is telling me nothing except it can be busy..not down or anything. My phone is any not registered to network

  • MichellAllgood Michelle (@MichellAllgood) reported

    @Ofcom Is it you who I would need to raise a complaint against @tescomobile? I took out a new contract on 24th November & they still have not transferred my existing number. Pac code was given on 25th November. Totally unacceptable! @MartinSLewis can you advise please?

  • RishiSack SackRishi (@RishiSack) reported

    @tescomobile @TrussellTrust your service sucks. been waiting almost a week for you to port my number. every day im told 24 hours it will be done. the customner service cut me off, lie to me and dont fix the problem. so not only do i not have my old mobile number the new tesco one doesnt let me make calls.

  • vannerbird ☀Ange☀️ (@vannerbird) reported

    @tescomobile Hi Emily. The status checker has been saying similar for months, all through summer since Ive been checking it. Others in the area have been checking it and complaining to O2 for quite a while. Apparently the mast is on someone's property and it's never been fixed.

  • mev202 I'll take you to the 7 seas of Rhye. (@mev202) reported

    @tescomobile No, that's an excuse. The local mast has been broken for months now. It's not good enough.

  • wleer72 wayne:of the rigden family (@wleer72) reported

    @tescomobile can you please explain to me. I work in tonbridge Kent and by 7.35 am every day I lose signal to the point even Google won’t load. I get no improvement until I leave tonbridge and go home

  • mnewell23 Michelle Newell (@mnewell23) reported

    Absolutely disgusted at the lack of customer service from @tescomobile Haven't had a reliable phone for 5 months and have received no compensation

  • mev202 I'll take you to the 7 seas of Rhye. (@mev202) reported

    @tescomobile Nice try, but actually you're unable to offer any service. That is not acceptable.
