    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

  • RWF86 ROBERT FOSTER (@RWF86) reported

    @tescomobile To be fair, every time I renew my contract with tesco the price goes down.

  • TheTethernator Altcoin Scientist (@TheTethernator) reported

    @tescomobile I was with this company for 7 years, I went to renew/upgrade a contract with them and they offered a deal of iPhone 7 on a 3 year contract. I asked can the term not be reduced because I’m a loyal customer or can I pay less each month? They took off £1/mo. Terrible company. AVOID

  • Abu_Haneefa2 Abu Haneefa (@Abu_Haneefa2) reported

    @EE @MrJPC123 Not really, we don't know what or how much the price will increase by beforehand, if other providers like @tescomobile can fix their prices then you can too. And your prices have never been fair, your the most expensive network compared to all others. So please stop this stuff.

  • AnnReyn75876642 Ann Reynolds (@AnnReyn75876642) reported

    @tescomobile Personally I'd rather you spent some of your profits on more masts so I could at least rely on a decent signal strength more often.

  • JennieM37925513 Jennie Martin (@JennieM37925513) reported

    @tescomobile I may have missed something so raising the question, has anyone else not had 4g for a while. I have no network outside the house. Bills paid up to date never paid late?!

  • Peter14229846 Peter (@Peter14229846) reported

    @tescomobile It’s just a shame your network is trash. I was with you bought a new phone (iPhone 13 pro max ) went on sim only and I was getting call drops daily my friends also had same issue with Tesco. I called up customer support and they told me there was an issue with my brand new phone

  • viking_northern Northern viking (@viking_northern) reported

    @tescomobile I know how much you took off me for using my phone abroad for 15 seconds. Despite the account supposedly having a £40 user limit. I’ll never use Tesco mobile again.

  • ginsoakedbloke1 ginsoakedbloke (@ginsoakedbloke1) reported

    @tescomobile 1p mobile. Cheapest around and OK. service Let's hope they last

  • AnnReyn75876642 Ann Reynolds (@AnnReyn75876642) reported

    @tescomobile It says a local.mast is not working as it should. But this signal here is hit and miss all the time. Every day.

  • Siorsid Siorsid (@Siorsid) reported

    @tescomobile I left ages ago because you were never interested in helping when the signal went down. Now with Sky using same O2 network & give free data when signal drops. I get 4 lines with 2gb & 1 with 8gb = £24 per month. And all data roles over. Beat that & I'll come back to you.
