In the UK 1.5 million homes have no connection to the internet. That’s why for every plan purchased with us this Christmas, we'll donate free data to someone who needs it. We're better, connected 📲 o2uk.co/3DcxoLl #O2DataPledge

@O2 I mean, you could start with actually answering the phone to existing customers! And after 3 days of getting cut off ,I get through to the rudest most ignorant person ever. Awesome.

@O2 Your roaming services policy changes in the uk is unfair and borderline criminal. Your customer service "whatsapp" is appalling. Give me an email addess i can raise an official complaint to.

@O2 I've spent literally hours trying to get a chat with advisor or find a phone number for help. My new phone is dead until you activate my number. Waited 2 days.

@O2 Whats wrong your website I can't see my bills or contact anyone? The website appears to be down, are you going under?

@O2 I don’t have signal in my house today 4 numbers all dead..why?

@O2 Hi, I used to be o2 customer but left in September. I found out the O2 still charging my account as I would be there customer. Why? How can I claim my money back for October, November?

@O2 Hi O2 ordered samsung zflip 3 said was in stock for next day now its saying out of stock and that it's been ordered from suppliers how long is this likely to take

@O2 I have o2 chasing me for a phone contract that has been opened in my name and address I contacted your team in the beginning of November and still the fraud team have not contacted me get letters daily chasing payment and threatening legal action never dealt with such a company

@O2 Great idea. Now can you make it possible please for O2 customers to donate all these free coffees and Greg’s treats to the homeless? It would be great for everyone involved

@O2 Faulty phone given to my son at Christmas. Been hung up on 4 times...just so fed up wish I hadn't chosen o2 now

@O2 Meanwhile, paying customers wait forever to speak to O2 via chat. We just need to cancel our Apple watch data plan. If you don’t want to spend money on staff so be it, but at least give us the option to cancel services ourselves.

@O2 How can I easily make a complaint? Made the huge mistake of upgrading with o2, total disaster, I’m out of pocket due to misinformation and poor customer service. I was told I’d receive a call back on Monday, I’m still waiting.. oh then there was the non existent loyalty discount

@O2 How do I get you to listen or take notice? O2 sent out a sim through Virgin media - which we did not want as it's £13 more a month than our current sim. We returned the sim IMMEDIATELY. You took £25 from our bank account last month - and I cancelled the DD.We are now 'in debt!'

@O2 My power was off but back on now. Why does my phone have no service?
