    @tescomobile have an elderly customer who has put my landline into their mobile phone, their escalated "customer care"suggestion to resolve the continuing nuisance is to call @DC_Police and get them to provide help to a @tescomobile customer Unhelpfully hiding behind GDPR

    @tescomobile How about you fix your data usage issues

    @tescomobile If O2 doesn't work despite trying different phones, then neither will Tesco! No need for the cooling off period! Work mobiles are other networks so will probably be best just moving to one of them.

    @StaceyTester2 @thismynewhandle @tescomobile Stacey, you are the sort of customer Tesco loves.

  • newfreederry420 Jackie Mackis (@newfreederry420) reported

    @tescomobile Thoughts go out to ronaldo at this tough time for his family. Why are @Tesco silent instead of vocal about their support. I wont shop @Tesco any longer until they make clear whether they support CR7 or not.

  • wildlifelover0 Wildlife mad (@wildlifelover0) reported

    @tescomobile Poor signal ever.

  • howdoihev Hev 🌻 (@howdoihev) reported

    Counting down the days until my @VodafoneUK contract is up and I can switch to @tescomobile! Shocking coverage, appalling customer service and they’ve upped the prices mid contract. 33 days to go until my Clubcard price contract 💙

  • Kiff Kiff Lloyd (@Kiff) reported

    @rya89160347 @tescomobile I used to be on EE which was decent coverage, since changing to Tesco it’s garbage in every part of the country I’ve visited (significantly worse than other friends on O2) I suppose you get what you pay for, I won’t be renewing I don’t think…
