    Thank you so much @tescomobile for sorting out and reimbursing me for the scam texts I received yesterday. Yet again wonderful customer service from @tescomobile

    @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

    @tescomobile Signal is actually **** lately 🙃🙃🙃

  • TJKenny_ T (@TJKenny_) reported

    @VinnieLouu @Gremlimuk @tescomobile To me it sounds like 1 of 3 things 1 - Could be the phone (I very highly doubt it is but its known to occur 2 - The SIM could've gone faulty, we had a bunch go bad around December time I think 3 - Could literally be a case of taking the SIM out, cleaning it and popping it in

  • VinnieLouu Katie (@VinnieLouu) reported

    @Gremlimuk @tescomobile I’m sure the ombudsman would love to hear about this. I shouldn’t have to drive away from home to be able to use my phone to make calls. I’d be ****** if it was an emergency! The fact that no WiFi call assist is available is also disgusting. Rip off company!

  • DaveFleming68 Dave Fleming (@DaveFleming68) reported

    @tescomobile is there an issue with the account website? It won't let me add a data bundle

  • VinnieLouu Katie (@VinnieLouu) reported

    @tescomobile In the whole area. It’s definitely not my handset, I’m up to date on software updates, I rest the network settings, I’ve restarted the phone. I’ve done everything. Even when I do get bars appear, I still can’t call or receive calls. I don’t pay £60+ a month for 3G and no service!

  • ConnorMcUK1 Connor McNamara (@ConnorMcUK1) reported

  • UKVOICE4 UK VOICE (@UKVOICE4) reported
