    @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

  • x_x_stella_x_x stella (@x_x_stella_x_x) reported

    @tescomobile I did question it but was told it would still be applied. All very well to offer to cancel it but Black Friday deals have finished now and it was my daughters birthday present. Shall I just take it back off her? 💩 service all round. I’ve been a loyal mobile customer for years

  • x_x_stella_x_x stella (@x_x_stella_x_x) reported

    @tescomobile Oh really??? I bought a “Clubcard” deal iPhone 12 on Black Friday but the sales man made a mistake and didn’t apply my Clubcard so I never got the deal. Fast forward and I’m billed for the full price and after a lot of “I’m sorry’s”, there’s nothing we can do now but cancel

  • x_x_stella_x_x stella (@x_x_stella_x_x) reported

    @tescomobile I spent one and a half hours this morning in tesco phone shop then another hour with customer services. Everyone was sorry but useless to help me

  • KateBlahRah Katy F (@KateBlahRah) reported

    @tescomobile Hi Sean. I’ve had a quick look, I don’t know that this authority can help me. Basically I have been billed since February £4.50 twice monthly by a premium number that I have had no contact with. I have never texted them and they don’t text me. It’s a scam

  • cassietaylorllb cassie (@cassietaylorllb) reported

    @tescomobile after delivering our new phone to the wrong address, pretending to investigate, police proving it was returned to you, you still refuse to replace the phone and bill us for one we never received, Great customer service!!

  • BernReturn ReturnOfTheBern (@BernReturn) reported

    @tescomobile hello I just did an online top up of my Tesco mobile phone, paid £10 and I have the receipt, but every time I've tried to call my voicemail to check it, it says I need to top up my phone...which I just did. Help ASAP!

  • ObsessedCity ffafbc (@ObsessedCity) reported

    @tescomobile is your mobile app down? I’m trying to add data but it’s saying there’s a glitch and to call customer care on 4455

  • MartindeakinMd mar dea (@MartindeakinMd) reported

    @tescomobile Yeah the problem is the master number needs to be my number but alas I'm not with Tesco. Don't worry Rob managed to log in and get PAC codes sent to relevant phones. They in turn will text them to me!

  • KateBlahRah Katy F (@KateBlahRah) reported

    @tescomobile Also, I have never received any texts from this number. How will sending STOP help? I don’t receive texts. I don’t understand how I can be billed for this, when I don’t receive or send texts to this number. How is it possible.

  • Lainie1970 Lainie Rogers (@Lainie1970) reported

    @tescomobile Hi I'm a Tesco Mobile customer. I have received a text saying as a loyal customer I have received a £5 e voucher. Can you tell me if this is legit. I called customer service but the guy wasn't very professional and was vague. Worried its a scam
