  • MarleyBoo1 Against all Paid Shill's 🥊 (@MarleyBoo1) reported

    @olliechelsead @O2 They offered me a measly £10 after I finally managed to get through to customer service. 02 do not make it easy to get support or to register complaints. BTW I told them to keep the tenner. I want to break my contact and go with EE.

  • AmyCDoore Amy Doore (@AmyCDoore) reported

    @O2 can you tell me why at night I have perfect mobile signal and then come the morning, when I actually want to use my phone, I have terrible signal? Your signal checker says it's good signal strength, I can tell u now there is nothing good about it!

  • MrBlackPoplar Scott Johnson (@MrBlackPoplar) reported

    @O2, Hi there, We saved free cinema tickets on my wife's account, and they just disappeared? It expires tonight. We were planning on using it for tomorrow. A) what went wrong, and B) can you help?

  • SBMBMX Clark Thurman (@SBMBMX) reported
