    @tescomobile The price “changes” I’ve just been informed of are massive increases - one was 400% - am I able to cancel my contract before it is due to end? I don’t approve of price gouging.

    @tescomobile Its not a very good security protocol when you need to access your account to look at phones because your current phone is broken.

    @tescomobile is there a problem on your website? My OH is unable to complete a transaction. Been trying for 30 minutes.

  • Tesco Tesco (@Tesco) reported

    @RABCJ @tescomobile Hi, if you DM me I can help ensure everything is okay on the Clubcard side of things and try to give some specific information. Even if the problem is not something I can directly sort, I can hopefully identify what the issue is and who you need to speak to to get it sorted. Lee
