    Check your bill if you took out a contract with @O2 before 25th Mar they increased by #RPI April onwards. Whilst legally correct, I would suggest you don’t change your mobile contract until after 25 March each year to avoid RPI increases. Maybe @MartinSLewis help get the word out

    @O2 Hi, thanks the response. I’ve tried the website, and when I click on to see the offers it takes me to virgin media’s website. I click on the “I’m an o2 and VM customer” option there, then it asks me to sign into o2 so I’m trapped in the cycle of signing into both sites

    @O2 This is why i cannot survive in a modern environment, it was right there the whole damn time 💀

    @O2 Where do I go when I am getting no help from O2 with their dreadful service? I have contacted the complaints team which has been ignored. Have yo say O2 really is the worst network I have ever experienced.

  • andrew_conaboy Andrew Conaboy (@andrew_conaboy) reported

    @O2 @O2 I live in Germany, today I paid off my device, left o2-uk, was given my PUK code, closed my o2 account and inserted my German SIM. The PUK does NOT work. Now I have a phone which I personally own and no way of using it. I need help urgently.

  • thesockpuppet Hi, my name is Nic 👻 (@thesockpuppet) reported

    @O2 your signal checker says I should get strong indoor 4G at my home, but I get 1 bar of 3G and cannot connect to the internet without WiFi. Why is the signal map so inaccurate?

  • AJM100000 AJM70 (@AJM100000) reported

    @O2 where is my phone? Supposed to be delivered today. Says on dpd o2 requested it back?! Nice to be contacted! Awful company

  • sputniksteve stephen (@sputniksteve) reported

    So, phone says it has full 4G but when I make a call it drops to 3G. Aside from the generally poor signal, this is irritating. @giffgaff @O2
