    @ohchoya @tescomobile I have a problem with my phone contract

  • C_Kneer Charlotte Kneer DL (@C_Kneer) reported

    Yesterday I tweeted we need new phones/sims for women at our refuges. @O2 and @tescomobile responded 👏. Will keep you posted if they help. This could make a difference to all refuges in the UK at relatively little cost. Other providers, can you help?

  • richard0927 Richard Lane (@richard0927) reported

    @tescomobile @Tesco I’d put a few random items in my basket to reserve my slot. Now I can’t login to do my real shop. Can you please provide an update of what is happening?

  • Helprequired1 T-wuncle (@Helprequired1) reported

    @tescomobile Under your "contact us" page - it says "You can contact us by phone, email, text service, letter, web chat or via social media. Look at our Contact us page for details" Where is the email link ?

    @tescomobile Also if you check the log of the conversation I had with customer service on the day. If you have a system that tells you you’re running out of data, so you immediately top up &still get charged, the system is wrong.
