    @3Luv102 @WhichUK @O2 Do you have a problem just in this one location where the engineers are aware of even when you're out and about or out of the area? - Rob

  • BensonMelb66 Melanie Benson (@BensonMelb66) reported

    @O2 absolutely disgraceful service from 02 mobile. Upgraded to IPhone at Christmas for our sons Christmas present; 6 months later and still no network.

    @goblinshagger @O2 I've been with o2 since before they were o2. But over the last few years they have gone down hill. When they moved their call centre from Manchester to where ever it is now is probably about when.

    @O2 on hold for ages to then be disconnected! Please contact me re my DM. AWFUL services

    @tescomobile @WhichUK @O2 Few months ago but it's got worse. My phone often just goes to answer phone due to no signal so I'm missing important calls (such as doctors, work calls etc) Messages don't often send, I'm replying on WhatsApp (when that works!). WiFi isn't that good and my phone data never works

    @tescomobile @WhichUK @O2 There is an issue, I've already followed your steps. Unfortunately that does not help me out and now I'm paying for a service which isn't up to scratch!

  • goblinshagger Pheel-it Steak (@goblinshagger) reported

    @SimonCBondar @O2 No ******* clue! Ordered it this time last week, paid for next day delivery and they **** it up.. now tell me its processed (not updated my end) and given me **** all confirmation of this

  • johnyev 🇬🇧 Sir Non Chorley. No vax passports (@johnyev) reported

    @O2 my advice to anybody thinking of using o2 is DON’T unless it’s the last one in your area with a signal? Even then just move house it’s easier!
