    @vodafonebiz insurance manager is supposed to be getting back to me today. On the @tescomobile number I bought 2.5 years ago when it took vodafone insurance nearly 6 weeks to replace a phone then. That is a 100% fail rate on their own SLA.

    @tescomobile Hi. I ordered a new SIM card for my phone last week via Live Chat but two have been sent out. One I've had but because there's another on the way I've no service from the first one I received! I only asked for one new SIM!

  • BKDilse BK (@BKDilse) reported

    @tescomobile Been happening for 2 weeks, on 3 phones all on Tesco Mobile. Works fine on WiFi, doesn't work on Mobile Data, unless I VPN to another network. No point in a screenshot, as it only shows camera connect failed. I'm not an end-user, I'm a IT Consultant, so have carried out tests.

    @tescomobile Thanks for the reply, how do I cancel, I'm within the cooling off period.

  • SWstudent78 mel (@SWstudent78) reported

    @tescomobile Contacted on social media as do not have a spare hour to hold!!! I only want the call you promised me 2 weeks ago so don't make out I'm making awful demands.. I am sick of chasing you people.

  • gomark Mark! (The Herald Angels Sing) (@gomark) reported

    @tescomobile Yes, I’m using my home broadband network. (My mobile contract is unlimited minutes and data, but obviously I haven’t had any of either so far this month, at least not where I live. I can drive about 4 miles to get a signal but only fleetingly.)

  • fred280 fred smith (@fred280) reported

    @tescomobile Hi, I have been with you since the 8/12/21, I have bought a samsung galaxy watch from Amazon, when I try to setup a mobile plan it says I need a QR code or activation code from my service provider, can you supply me with one, if not I would like to cancel my contract

  • SWstudent78 mel (@SWstudent78) reported

    @tescomobile 2 months of no signal now.... the team still haven't called me... still paying a small fortune for 5 contracts we can't use at home... have @O2 got "permission" to fix the imaginary down mast yet?

  • SWstudent78 mel (@SWstudent78) reported

    @tescomobile I don't have a link I can't find it and I'm busy so don't have time to sit waiting. Don't be rude! You're the ones messing me around and also taking money off of me whilst not providing a service whilst also lying repeatedly. No need to be rude to me!
