  • 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

    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 😡

    @tescomobile She has been waiting for an e-mail with instructions since yesterday afternoon... still nothing and zero signal; she is now regretting to switch from EE for the sack of more gigabytes (which she cannot use for last 2 weeks). Disappointed indeed

  • weirside2000 David Sink (@weirside2000) reported

    @tescomobile I’ve contacted you many times over the last 2mths, always being assured you’re aware of the problem;yet here we are my phone still comes up with no caller ID, I’m trying to run a business it’s very difficult to do. I await your reply.

  • edel_thom Edel Thom (@edel_thom) reported from Stittenham, Scotland

    @tescomobile Text messages on my iPhone are flagging as unsent but are still being received? iMessage is not affected. I have tried resetting phone settings and it’s not resolved. Is it a network issue ? Thanks

  • CarlMalkin6 Carl Malkin 💙 (@CarlMalkin6) reported

    @tescomobile I have been trying without success to update my bank information for payments for a week. The problem is the shady company you use to process payments "Mi-Pay Ltd" who can't even spell in English. They don't wish to be contacted directly as their email box is "full".

  • Brian_Moule1 Brian Moule (@Brian_Moule1) reported from Kidderminster, England

    @tescomobile Could I get some assistance please? I regularly am unable to get signal in places where friends/family have strong signal. Also apparently I have 4G but been unable to use my phone today at times Need more than club card points as an apology when this is reoccurring

  • LucyVictoria_xo Lucy Victoria♡ (@LucyVictoria_xo) reported

    @tescomobile have been nothing short of a shitshow!! I’m so angry with the customer service i’ve received with an issue thats taken over 4 months and now, after DELETING MY NUMBER, they’re refusing to call me!! It’s made me want to move away from @Tesco completely! 😡😡😡😡

  • Purps3631 Kelly Smith (@Purps3631) reported

    @tescomobile i have recently changed to you from virginmobile as their signal was a disgrace, i however now cannot send sms/mms messages, i can voice call no problem, i tried to get the setting sent to me via the link on the website but this does not work, can these be sent by u?

  • louiselavin9 louilav (@louiselavin9) reported

    Have a tesco sim which we hot spot from, was told today I had used over 1 tb, It affects other users, is this right? @tescomobile @ThreeIreland #help #Tesco #three

  • mev202 You and me, we are destined you'll agree. Bijou. (@mev202) reported

    @tescomobile I am so so desperately disappointed with how terrible your phone signal is. I can't use my phone at home and it has been months now. I try and make calls and it just drops, I want to leave, but my contract has months on it. It is useless.

  • BenWinterburn Ben Winterburn (@BenWinterburn) reported from Leeds, England

    @tescomobile I have recently upgraded my sim only contract. I asked to keep the same number and was ensured this would happen. Instead my old number has been disconnected which is the complete opposite of what I asked for. This has been terrible service. Please get in touch.
