  • 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 😡

  • 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

  • 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?

  • Lindsay_Brunt Lindsay Brunt (@Lindsay_Brunt) reported

    @tescomobile Well it’s 10 minutes until they close and no call so it’s not going to happen! I’ve raised it again to @Ofcom again now! Whole 8 weeks has been frustrating and service is awful. Can’t wait to leave the network!

  • Lindsay_Brunt Lindsay Brunt (@Lindsay_Brunt) reported

    @tescomobile Ive been waiting all day what time does it close? Your advisors on the phone and chat are most unhelpful!! frustated at your service once again!

  • danjkahn Dan Kahn (@danjkahn) reported

    @tescomobile Presumably if I tried to upgrade one of my existing contracts I’d have the same issue?

  • grumpygal1 Michele Hodgson (@grumpygal1) reported

    @tescomobile @TrussellTrust Will never recommend Tesco Mobile. Persuaded husband to leave O2 after years. Got contract and PAC code from O2 to switch number. Used new Tesco phone with old number for a couple of days but had issue with device. Now Tesco unable to put old number on new device. 1/

  • APhillips1962 Andy Phillips (@APhillips1962) reported

    @Lindsay_Brunt @tescomobile Have had that many promised call backs that never happen rang 4455 last night told it wasn’t on record to ring me lol can’t make it up this week alone two messages from care team to concerns team I sent three emails no response

  • grumpygal1 Michele Hodgson (@grumpygal1) reported

    @tescomobile @TrussellTrust Was told to go to Tesco Shop start and another contract to get old number on new phone's SIM. Did that then spent ages on phone to Tesco trying to get this done. Now have message to phone Tesco because there are issues! FIASCO.

  • berta_pxx roberta paterson (@berta_pxx) reported

    @tescomobile I have just been told there is issues and may take longer than 24 hours..

  • isaac_t_6 Isaac Thompson (@isaac_t_6) reported

    @dawnfxx @tescomobile @Tesco They give users a lot of runaround on issues like this, You can message “syncunlocks” on instagram to get it unlocked, they helped me out with mine

  • danjkahn Dan Kahn (@danjkahn) reported

    @tescomobile @juliagoolia1982 If this can’t be fixed then I’ll be setting up this new contract elsewhere and taking my 3 existing contracts with me. The most concerning thing is that no one who works for you has a clue what the issue is. I’ve even offered to share my equifax report to prove it all matches!

  • Georgiagiraffe Georgia Cambridge 💙💛 (@Georgiagiraffe) reported

    @tescomobile thank you for closing my account but as I’ve tried to cancel it myself since November, not used the phone since then, yet you tell me I owe £25! Then asking me how I’d like to pay it?!
