    @tescomobile Hi, can you tell me if Tesco intends to support Apple Watches any time soon on a cellular level. If not why? O2 network is used on Tesco mobile…. How far apart can an iPhone be away from a watch if used and will your Apple Watch connect to all available WiFi?

  • HAndTheElements Hegsy & The Elements (@HAndTheElements) reported from Cardiff, Wales

    @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

  • TRHComposer Thomas Richard (@TRHComposer) reported from Cardiff, Wales

    @tescomobile my mobile data has just stopped working. Still got over 10GB available to me though. Is there a Network problem?

    @tescomobile I can’t call or receive calls today, get call fail on them all but I’m able to text and use data without a problem. Is there a problem in the CF63 area?

  • soozles_ Soozles (@soozles_) reported from Barry, Wales

    Seriously getting sick of the awful signal from @tescomobile 4 years I’ve been a customer and have 4 contracts with you spending &150-£160 a month and it’s getting worse everyday! Been trying to speak to someone all day (friend) and constantly getting call failed 😡

    @tescomobile Yes! Tesco advised me they booked it for today on 20th December.... but no collection today as promised as tesco only booked it yesterday (10days later) very poor service, no explanation or anything. And still no DM reply

    @tescomobile wonderful company really look after customers. 2 weeks of problems still not resolved cost me god nows how much so far and get offered 1000 Tesco points £10 . Oh and that’s off my bill so still intend billing me for phone I can’t use . Excellent customer care

  • Robert_May_ Robert (@Robert_May_) reported

    @bt_uk I'm not a BT customer, nor's she. Somehow BT has got itself in the middle between @tescomobile and @TalkTalkBizCare to create a purgatory that cannot be stopped Tesco are hiding behind GDPR, its nothing to do with Talk Talk- you've created a service you've not thought through

  • stevecdiscord Steve | Youtuber (@stevecdiscord) reported

  • Lindsay_Brunt Lindsay Brunt (@Lindsay_Brunt) reported

    @DPDgroup_news @tescomobile Yes I will but I've already called your customer service team who didn't think was an issue which is worrying

  • robsimpson2712 Rob Simpson (@robsimpson2712) reported

    @tescomobile Does anyone else have customer service issues with Tesco Mobile? I’ve been trying to sort an issue out since 29 October but keep being told to wait 24 hrs. Their 4455 service is so unreliable with so many false promises. I hope that little bit helps you all.

  • robsimpson2712 Rob Simpson (@robsimpson2712) reported

    @tescomobile @Suzywoo16 Nobody expects poor customer service but unfortunately Tesco Mobile are probably one of the worst. Been waiting since 29October and nothing resolved. Despite promises. Always got to check back in 24 hrs🤪🤪🤪🥸🤪

  • APhillips1962 Andy Phillips (@APhillips1962) reported

    @Lindsay_Brunt @tescomobile Another day has passed an still no phone number still no reply to issue. Why should we have spend time on phone decent customer service would update you on progress , but sorry we’re talking tesco mobile spect sod all. SHAMBOLIC COMPANY

  • APhillips1962 Andy Phillips (@APhillips1962) reported

    @tescomobile is anyone responding to tweets today? It has been 24 hrs since had any response from any customer service rep.
