    @tescomobile It really is the last time i buy anything from Tesco. I won't shop at your supermarkets or buy petrol at your garages. I'm shocked and fuming that you won't do anything with a defective phone that obviosuly has a defective battery and it's not even paid off. Shameful service.

  • andy_uk44 I am just me (@andy_uk44) reported

    @tescomobile Too much and not enough to give a better service to those who suffer very low signal and @TelefonicaUK is one of those who won’t do anything about it

  • ExPursuedByBear Tom Driscoll (@ExPursuedByBear) reported

    @tescomobile Don't you share O2's network?

  • budgiesmuggle45 budgiesmuggler45 (@budgiesmuggle45) reported

    @tescomobile I'll lodge a complaint with the Financial Ombudsman. You've basically sold me a defective product as the battery should reasonably be expected to still function after less than two years. I'm quite sure you'd be unhappy if you bought a new phone and the battery died so soon.

  • 21EmoSavage Emo Blaze 😔 (@21EmoSavage) reported

    @tescomobile Literally never dropped it i secure it in a locked cabinet when not on the phone and handle it with care always have gloves on so how come it broke I think that's a you problem

  • 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.

  • contactpc PC (@contactpc) reported

    @tescomobile missed my #flight because I’m not receiving SMS on my phone and the issue is still ongoing. All recommended action has not resolved the issue. Can I please port my number if you cant resolved this issue by this Friday.

  • pabakz Paul B (@pabakz) reported

    Many of the deals are for resellers such as @tescomobile or @lebara Do these resellers generally have full access to the parent network or is their access constrained in bandwidth or service restrictions?

  • KevinDeakin11 Kevin Deakin (@KevinDeakin11) reported

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