  • 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

  • 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 😡

  • 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?

  • KeithDManning Keith Manning (@KeithDManning) reported

    @tescomobile I think it’s a real shame that you don’t take fraud seriously as a company. 7 weeks and still waiting for an ‘urgent’ call back from you. Very glad you aren’t my network.

  • Suzy_dashey Susan (@Suzy_dashey) reported

    @tescomobile can you help? Need advice on how to cancel contract for someone whom has lost capacity. Or if any of my medical friends can help!

  • tinmanrocks tinman (@tinmanrocks) reported

    @alcatelmobileuk @tescomobile I have an Alcatel 1B 2020 32GB. One of the Android updates broke the option to increase font size above 130%. Google released a fix for this to manufacturers last year. Nokia & others have released a fix for their customers. Why has Alcatel not fixed this?

  • aintitdrew Russell (@aintitdrew) reported

    @tescomobile I have been a monthly contract holder for five years after this contract is finished I am quitting, terrible service, absolutely appalling

  • afl2277 ☀Ange☀ (@afl2277) reported

    @tescomobile Thanks Callum. I'm looking to cut household bills before April when some horrendous rises kick in. Getting rid of my landline calls would be a big help. Unfortunately not everyone has a good enough signal to allow a clear call each evening so cannot cancel the landline yet.

  • Anndavies427 Ann Dawes (@Anndavies427) reported

    @tescomobile can someone help to cancel a contract for someone who has lost mental capacity. Contract not been used for several years so cancelled the DD. Now being chased for payment. Customer service won’t help contract as not in my name.

  • ONeillHCO H O'Neill (@ONeillHCO) reported

    @tescomobile @Tesco Thank you for your after thought but a bit late now as the price has now gone up an extra £10 per month. It shouldn’t be this hard to get help to give you business!

  • AberJohnny John Malcolm McMenemy (@AberJohnny) reported

    @tescomobile In the big scale of things, it's not a great deal, but just wish major companies would do what they say they would. Never mind - soon be spring.

  • d_scott84 David Scott 🏴󠁧󠁢󠁳󠁣󠁴󠁿 🐿️ (@d_scott84) reported

    @tescomobile Doesn't show any issues, just some rubbish about data. I do have to laugh about the 'good 4g' bit because that's a massive lie
