Absolutely useless... the customer service team has been extremely unhelpful. I have been trying to transfer my old number to O2 for over a week and they have failed over and over. It is supposed to be a simple automated process you complete online. Instead, I have spent over 6hours on the phone to them trying to resolve it and still to no avail.
