    @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?

  • 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

  • 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 I’m trying to upgrade my phone and it’s saying the phone I want is out of stock, so I click the thing to get notified when it’s back in. Then it emails me at midnight saying it’s in stock, so I go on the website to order it and it’s saying out of stock?? Help pls

  • Ed_Osagie Edobor Osagie (@Ed_Osagie) reported

    @tescomobile Hi, I am a tesco Ireland mobile phone customer. I wish to move to tesco UK cos I've just moved into the UK. What should I do? I need to make this change ASAP please

  • sazz8 Sara Miller (@sazz8) reported

    @tescomobile I currently have £30 in the broken phone.

  • ExpatEcosse Parole D'Expat Écosse (@ExpatEcosse) reported

    @tescomobile They told me to contact you. You guys needs to speak with each other. I have paid for an order up front then was told it could not be fulfilled and now I have to chase for a refund! It is unacceptable! What kind of service is this?

  • mrsverypicky Sue Reeve ♥️🧡💛💚💙💜🇪🇺🏳️‍🌈🕊️🕷️ (@mrsverypicky) reported

    When your phone decides to give up the ghost, 4 mths ahead of being able to upgrade. (Occasional intermittent issues, nothing major.) Unplanned trip to @tescomobile to fork out for early upgrade. Except major issues due to not remembering all passwords. OH now trying to sort out.

  • MaulaJatt18 Maula Jatt (@MaulaJatt18) reported

    @tescomobile after speaking to Callum today who refused me his manager, Paige, I realised I have been mis-sold into a contract which I did not ask for. I have been charged premium texts when I had a safety buffer and TM will not refuse. More shocking is the poor customer service

  • Cookie32243716 Cookie (@Cookie32243716) reported

    @tescomobile seriously need to enable their network to make use of wifi calling. Tesco being left behind by all other networks

  • essexoldbird Essex do-gooder Oldbird 🇪🇺 💙💙💙 (@essexoldbird) reported

    @tescomobile @O2 I haven't been able to make calls or pick up voice mails for weeks in my local area. Paying for a service that I'm not receiving. Complaints link on website is a 404. #notgoodenough

  • MaulaJatt18 Maula Jatt (@MaulaJatt18) reported

    @RobBell24009932 @tescomobile Their customer service has gone to the shitters. U probably best switching providers as their customer service sucks. I was refused a manager today despite asking 3 times and oh yes I was mis sold a contract to but advisor couldn't do anything neither let me spk 2 a manager

  • ont_stoop TheDarkenedDoorstep💙 (@ont_stoop) reported

    @tescomobile I needed to reset my apps to their factory settings to resolve problems with my settings. An unfortunate side effect of doing this was wiping out my PAYG balance which is more than annoying so can you possibly restore my balance.
