  • RachelAshleyVox Rachel Ashley. 3.5%. FBPA 🎧🎤 #StandUp (@RachelAshleyVox) reported

    @pxthomas93 @tescomobile Yes. I have experienced similar before when a venture capital company trashed a tech start up. This was years ago, they were so ahead of their time, it was a tragedy. They were one of the first companies to sell online. I was the voice that guided the customer.

    @Callum_loves_u @O2 @tescomobile ey they use the same network technically, tesco piggybacks off o2 like giffgaff does

  • binaryfive70 Jody Stephen (@binaryfive70) reported

    @tescomobile Please can you stop scaring the bejesus out of me with Emergency Alerr tests? I don't mind then generally, in fact I normally enjoy then, but 3 in a day is a bit excessive.

  • klambechops Karen Laverty (@klambechops) reported

    @tescomobile Still waiting for my order and call back from your concerns team. Not good enough Tesco. Four orders, many promises of delivery - STILL no phone. Money paid several times. Formal complaint will be made later today.

  • BarbaraStraughn Barbara Straughn (@BarbaraStraughn) reported

    @tescomobile Hi Maria, I spoke to Customer support and they told me there were intermittent problems just 5 mins away from where I am so I guess that might be something to do with it.

  • chloeWSJ ✨Chloe✨ (@chloeWSJ) reported

    @tescomobile I’ve received a letter in the post telling me I’ve signed up to a Mobile contract with you when I haven’t done this myself, would you be able to help me? Many thanks

  • RichardHofman33 Richard Hofman (@RichardHofman33) reported

    @tescomobile I had never used this SIM since I bought the phone several years ago.But there shouldn't be given promises to activate SIM up to 24 hours once it was known about that. Certainly,I don't know how long a SIM activation process may last but they could tell me instead of a promise.
