I strongly advise not to take O2 as sercice provider of any kind! I have been using O2 for a 2 years with bo issues, yes, coverage speed and quality way below ee or vodafone, but it was okay for me. Suddenly, I had some rabdom purchase added to my account! I have contacted o2 refarding this mistake, they apologised etc...but it was only a lie. They suddenly closed my old accounts with them, just because I haven't paid for something I never bought, for their mistake. It took 8 months and ombudsman service fkr them finaly to close that mistake and compensate me! I have decided never again to use O2 services and wanted to pay for my actual closed accounts and move away. It was a nightmare! They messed up all numbers, couldn't provide information about how to pay it, they had no idea how much too! All they gave me some random numbers without any explanation! And when I paid it, they sold it to 3rd party debt collectors! How? It is all paid and they sell some random stuff? Try to talk to them, pointless. They just ignore you. Basically, there is no one to talk to anymore. I wanted to cover all what I owe to O2 and they made it nightmare by creating random numbers and ruining credit file, selling already paid accounts. If you really value quality and your time, you bot going to look at any Telefonica operations. BTW, Telefonica aka O2 were penalised by Ofcom for overcharging customers for things they never bought too. Don't go to O2!
