    @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

    Hello @tescomobile. Can someone please confirm or deny whether the #TescoMobile network is working in the area of #Redruth in #Cornwall?

  • clarepym Clare Pym (@clarepym) reported

    @tescomobile Yeah Calls work ok, texts seem to just fail to both send and receive to other networks but work between their phones which are both on Tesco

  • CraftyNigel Nigel Craft (@CraftyNigel) reported

    to look in @tescomobile store In Ely last night thinking about maybe a getting new phone and contract with them as my current one with giff gaff is rubbish, but the lady didn’t seem too interested in my custom saying their network was same as giff gaff maybe I should go to EE

  • CraftyNigel Nigel Craft (@CraftyNigel) reported

    Maybe I didn’t look rich enough , I went in enthusiastic willing to get a new phone and sign up for the right deal ,but she put me right off and she also said I should ring apple as my phone was probably broke,sorry @tescomobile Didn’t feel at all valued as a customer at all

  • Joserilinio Joe Riley (@Joserilinio) reported

    @tescomobile what a joke your roaming charges are, my wife is on the same end network (o2) and is charged 20p per MB where as you are charging £5 per MB. I know what I’ll be doing with my contract when it’s up shortly 👋🏼

  • Li11y80 Liz Cornell (@Li11y80) reported

    @tesco why is it so hard to return a phone? Been pushed between @tescomobile and yourselves, tweeted, phoned, waiting for calls and still no way to return this phone. Seriously bad customer service.

  • robd15361 Robd15361@gmail.com (@robd15361) reported

  • nickyhop1 nicola jane hopkins (@nickyhop1) reported

    @tescomobile Not sure how, you customer service is awful, I am trying to deal with you teams following the sudden death of my husband and have been treated appallingly including having all our accounts cancelled and not returning calls.
