  • 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

  • ObiWanGlyndwr Sir Owain 'Obi Wan' Glyndwr (@ObiWanGlyndwr) reported

    The £2.99 was taken in addition to the next monthly amount and still @tescomobile cancelled the account. A terrible action from a terrible company in time of national crisis. The relative in question could not call for help after a fall & this was due to the mobile being cut off

  • craigwalsh28 craigwalsh28 (@craigwalsh28) reported

    @tescomobile Yeah but your signal is bag of poop round here

  • Keg1985 Kate Garbutt (@Keg1985) reported

    @tescomobile Thanks for your reply Laura, looks like there's upgrades going on until 28th March - seems a long time to be with no signal though and with no advanced warning either.

  • budgiesmuggle45 budgiesmuggler45 (@budgiesmuggle45) reported

    @tescomobile Easy decision for me. Probably just cancel my direct debit, never buy anything from Tesco again and never buy another @apple Iphone. Businesses today are borderline scamming consumers. How can a less than 2yr old phone be unusable after 8 hours when it's not even used all day?

  • YourGoat4 YourGoat (@YourGoat4) reported

    @tescomobile Terrible service, its taken 1 month to be issued a refund, after stating 5 days.

  • ToOdiE1955 Toodie (@ToOdiE1955) reported

    @tescomobile My first tweet! Just spent approx 1.5 hours on the phone trying to resolve a billing issue. Had to speak to 2 advisors after being cut off after being transferred. I asked to speak to a manager - no managers available! Your customer service use to be impressive!

  • KevinDeakin11 Kevin Deakin (@KevinDeakin11) reported

    @haghxgus @tescomobile Why should I waste my time watching our web page? You lot will never beat gif gaf

  • gaz1094 gaz clifford (@gaz1094) reported

    @tescomobile my phone signal has been really bad over the past couple weeks barely getting 4g signal? Constantly on 3G or edge my partners on Tesco mobile as well and he has no problems with signal at all? Can you help?

  • AngeliqAngela Angela (@AngeliqAngela) reported

    @tescomobile I tried to buy bananas at your high street store but the self service till would not let me scan them and they're were NO staff around to help and I had to get my son so I ended up just taking them. Sort it out or you will lose out on more banana profits I am sure if it 😡

  • TownAbout TonyAboutTown (@TownAbout) reported

    @G_Force_Invests @tescomobile No, of course not! Tesco is well known as the Parasite Network. They ride on the back of the O2 network and run an operation with a few clueless people from their Welwyn Garden City head office . One will be from the bakery, another from the fish counter and one from cosmetics.
