    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

  • 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?

  • 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 😡

    @tescomobile is there a problem with the service around Cardiff? I've had no service for two days. Thanks.

    @tescomobile awful service, upgraded and phone arrives damaged and then when I try to get it sorted I’m passed from pillow to post and nobody is willing to sort it , will be cancelling the upgrade and looking elsewhere

  • HashDin Hashim (He/Him) (@HashDin) reported

    @tescomobile Hello! I did yes and I got a reply saying I'll hear back in 24 hours. I decided to do it again and got a reply this morning with a moving date. Thanks for the help.

  • BeverleyNealon Beverley Nealon (@BeverleyNealon) reported

    @tescomobile shame on you. After being told both my mobile phones were out of contract now you’re trying to charge me over three hundred pounds for cancelling early. It’s impossible to contact you by phone and your online chat can’t help 😡😡😡

  • sue_perkins Sue Perkins (@sue_perkins) reported

    @tescomobile Hi yes it is...we didn't want to turn that service off but a factory reset fixed the problem so now texts and chat are coming through from the right phone no. Thanks for your help.

  • Titch_7 Lauren (@Titch_7) reported

    @tescomobile Thanks for coming back to me. I visited the store at 6:50pm but only spotted your worker who was by customer service when I saw him. Have spoken to the team at Penarth who said they have to take phones back or something.
