  • black_labs_rule LooseHead(Ex) 🏉🐝 (@black_labs_rule) reported

    @tescomobile A saga of trying to cancel an upgrade placed 28/7. 29/7 Live chat - “it’s shown as pending. You’ll have to call the customer team” 29/7 Customer team call #1 “Can’t cancel till the handset is on its way. Call us when we tell you this”

    @C0urtneyEvans @tescomobile Does it sat you have signal but emergency calls only?

  • C0urtneyEvans Courtney (@C0urtneyEvans) reported

    @tescomobile are a load of absolute bollocks. Can’t get internet or signal anywhere. As soon as my contract is up, you’ve lost a customer

  • CryptoSystemNo1 The Crypto System (@CryptoSystemNo1) reported

    @tescomobile Liz is proof of why some people should not get jobs in customer service, when they defend their company so much when the company is so obviously in the wrong, you know their customer service is going to be absolute crap and you'll get nowhere with them!

    @tescomobile help I only keep getting 3 g . I’ve had a new Sim but it’s still happening any ideas?

  • Bert054 Bert054 (@Bert054) reported

    @tescomobile I’ve added 1gb data to my phone. Paid. But it says immediately that I’ve used the 1gb already. Please help.

  • Dan_Baynham95 Dan Baynham (@Dan_Baynham95) reported

    @tescomobile @O2 The 4G signal in and around Ely Cambridgeshire has been really on and off for quite some time now! This is quite frustrating because part of my payment plan is for data and half the time I can’t use it 😑😑

  • meggzzie Megan (@meggzzie) reported

    @tescomobile Hi, it's not my phone as my husband on the same network is having an issue. The 4g calling is a poor signal despite a technician saying it should be a strong one inside and out
