    @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

    @O2 I’ve had your lines drop me while on hold twice now. I’ve had to call you 5 times, spent hours on hold, and still haven’t had my issue resolved. Please can you sort it with me via email or text so I can stop waiting around.

    @O2 We never get far enough into the conversation for that. They announce they’re calling from o2 with new offers and at that point I tell them I’m not interested.

    @Liam_marshall2 @O2 @O2 is all this feedback being passed on to priority team?!?! No one is happy with this change. It’s clearly not working #bringbacknero
