  • Lisagoodey Lisa Goodey (@Lisagoodey) reported

    @tescomobile @WhichUK Too late Tesco, gave you a week to sort it, can’t wait for a fix that might never come, I’ve moved networks.

  • RossandLucinda The L. (@RossandLucinda) reported

    @tescomobile The only thing I will say its really bad practice to blame the bank they said my credit is fine its a tesco technical fault. And I've got a tesco insurance on this phantom phone now because over the phone sales the system allows me to go a bit further than in store.

  • VinnieLouu Katie (@VinnieLouu) reported

    @tescomobile @gerryculbert1 Don’t even believe their lies!!! 3 weeks later, and I’m still without signal and I’ve heard all the excuses under the sun. And conveniently I’ve dealt with “Liz” EVERY SINGLE EXCUSE.

  • KevinGibbins1 Kevin Gibbins (@KevinGibbins1) reported

    @Craigo71 @tescomobile @O2 New phone, 100Gb of data for £20 a month, 24 month contract, with 3. A couple of minor technical issues (mainly because I'm technically inept) which were sorted really quickly. Decent signal coverage. I was with Tesco but they couldn't match that.

  • loulour1982 🍒 Louise Rae  🍒🇺🇦🕊 (@loulour1982) reported

    @tescomobile I am losing patience now. Been unable to use phone since weekend. Sim swap completed. Not needed. Mast eventually found problem. Problem apparently fixed. Whole area cannot use O2. All your chat says is restart phone but then I start again. Offered cc points as comp

  • MrsHoopDiddy Mrs Hoop Diddy (@MrsHoopDiddy) reported

    @tescomobile ordered a sim on 7th June and haven’t had it yet! My current contract ends on Saturday so I’ll be phoneless unless I get it! Can you help?

  • HebbyGold SParker (@HebbyGold) reported

    Hi @tescomobile 👋 Got my new phone a week ago but not been able to use it outside the house as it won't switch from WiFi to 4g without a reboot. Then 4g just drops off. Support line says 'outage' and 'being fixed'. Is it? Not the best first impression for me. Please advise..

  • satclive8 steve varga (@satclive8) reported

    @tescomobile Yes, we tried this afternoon as well as resetting connections, standing on one leg and various other options. I’m now a week into my new contract and haven’t been able to issue mobile data. My last call to Help Desk resulted in a referral to back desk.

  • Jaibxxx Jamie bonner (@Jaibxxx) reported

    @tescomobile wow never experience such bad CS. I rung to query my bill, 1st caller line cut out she didn’t call back, I called back she hasn’t even left notes. 2nd lady thought she put me on hold while I listened to her whole convo of her mimicking me to her colleagues!!
