O2 a name synonymous for a cesspit. Due to a recent house move I was forced to move from EE to O2, and my god, I have never in my life experienced such bad, unhelpful and outright useless customer service. We are currently on day 7 without any service. I have been into the o2 store, been on the phone for hours, spoken on live chat, yet 7 days later, no one has an answer to why my phone doesn't work, and quite frankly no one seems to care. Please avoid at all costs, go to EE. The amount of suffering this has caused me in my personal and professional life is worth no sum of money. Go EE, and never look back to O2. What a useless establishment (as you can see from all of the other reviews)
