Awful customer service. Over my 2yr contact I contacted them around 3 times and always ended up speaking to someone who spent 15mins asking how are you today and the usual scripted sentences. That's after the long wait to get through the automated options. The price hikes during the contract were a rip off. I've tried to call and email to pay final bill but its impossible. The automated service on all calls reject you if you're not with O2 anymore, Social media replies are robotic and useless. I've had an email off them I can't reply to, I've sent an email to their complaints and still nothing. I'll wait until the 8 weeks and contact the ombudsman. Terrible will avoid forever.
