    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 😡

  • 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

  • nigelbendybus Nigel Smith (@nigelbendybus) reported from Cardiff, Wales

    Thank you so much @tescomobile for sorting out and reimbursing me for the scam texts I received yesterday. Yet again wonderful customer service from @tescomobile

    @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?

  • soozles_ Soozles 🏴󠁧󠁢󠁷󠁬󠁳󠁿💙 (@soozles_) reported from Barry, Wales

    @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?

  • JayneFallows Jayne Fallows (@JayneFallows) reported

    @tescomobile having problems updating my bill payment details on my account. Phoned customer service for help but after being put on hold for 10 minutes was cut off by your agent. Terrible customer service and now we can't pay our mobile phone bill. Please advise

  • shanes_loonie leah the loonie :)💚🧡 I miss my pops 💔 4.12.20 (@shanes_loonie) reported

    @tescomobile £13 a month with 60gb of data thought I was onto something until I realised the coverage checker lied to me and I got a crap signal

  • PrestoleeGreen Meema (@PrestoleeGreen) reported

    @tescomobile Well Rob It appears the engineers have managed to fix the mast and we now have a signal . So let's talk compensation 2 X Tesco mobile phones with no signal for over 5 days . How much do we get off our bills ?

  • Stephen63004212 Stephen Green (@Stephen63004212) reported

    @tescomobile Hi. I have just arrived in France but I have no data connection ( phone is showing 3G) - please can you help? Thanks

  • AidanLewis23 Aidan (@AidanLewis23) reported

    @tescomobile I’ve just been on the phone an hour trying to sort this. This is yet again a new complaint based on your service

  • m1key_m Mikey (@m1key_m) reported

    @snwkrwn @tescomobile Vodafone say that they go up in April as part of the contract - didn't think it would be 9% though! 5.4% to support the "rise in running costs" and 3.9% to "continue essential investment in our network as we expand coverage" apparently 🙄

  • OghamTheBold OghamTheBold (@OghamTheBold) reported

    @tescomobile Tesco - no lettuce 😢 can't eat phones - even with mayonnaise - CO-OP £2 you can buy a massive rug for £3.50 down the car boot

  • YvonneD66181707 Duchess Yvonne Davies (@YvonneD66181707) reported

    @tescomobile absolutely disgusted by your lack of customer service, the rudeness of your customer advisors on your customer service call centre, my friend is ill and needs ha refund for a faulty Nokia phone due to android update which has corrupted her phone, 1/2

  • GalloUK13 Gina Gallo (@GalloUK13) reported

    @tescomobile I am trying to connect with someone to get my upgrade. Please help me
