  • 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 an outage affecting NN7? Can’t make or receive calls.

  • grumpygal1 Michele Hodgson (@grumpygal1) reported

    @tescomobile I'm afraid that's not good enough. How can 'hoping' help resolve the issue?

  • TyneBridges JH #FBPE 🇪🇺 🏳️‍🌈 (@TyneBridges) reported from Gateshead, England

    @tescomobile That doesn't help as my account isn't showing me the date it started or expires. Where do I get that info?

  • simone_uncle Simone uncle (@simone_uncle) reported

    @tescomobile . Very unsatisfactory live chat this morning with one of your agents. First time I have felt unhappy with your service in over 15 years. Can you advise me of your escalation process so I can take this forward to the ombudsman ?

  • HDeFillemere Harriet De Fillemere (@HDeFillemere) reported

    @O2 & @tescomobile - large scale signal outage around the sellindge area in Kent. Especially dangerous as the electricity is also down, leaving no way to call anyone if there is an emergency.

  • vannerbird ☀Ange☀️ (@vannerbird) reported

    @tescomobile Done. If you consider how long I’ve been with Tesco Mobile, starting with a monthly rolling payment then moving to a 12month contract, do you honestly think I would have taken on the 12month one if I just had E or no signal? Please report it.

  • AllanMcLaughlin Allan McLaughlin (@AllanMcLaughlin) reported

    @tescomobile Yes. But the communication is awful. Can't get to speak to anyone in the UK. For the last 2 weeks, we've been told to wait for 24 hrs. I am missing calls every day. It's seriously affecting our working day. I have ZERO confidence in Tesco mobile.

  • LisaClooney Lisa Corcoran (@LisaClooney) reported

    @tescomobile @jtorrance89 Awful customer service, where you have to reach out to Twitter for answers

  • vannerbird ☀Ange☀️ (@vannerbird) reported

    @tescomobile I’ve done that Jade, still the same. Gone into town when there’s a working mast and got 4g and 5g with signal bars, so it’s not the sim or the phone. This mast has been causing trouble for over a year now, many in the area are affected. 1/2

  • CaroLou1234 Caroline James (@CaroLou1234) reported

    @tescomobile Is four days with no service acceptable due to “mast issues” which seems to be happening to my mum in multiple and geographically different areas?
