I'm not surprised to see the poor ratings. O2 is dreadful. I have 6 phones with O2 but now will seek to move all my business away...Its not easy though. Their customer service is a joke. The wait times are usually over 30 mins whenever I call. When you get though I find the line tends to drop before they have helped me and you start the whole process again. they give advice that their branches then say they can't fulfil. Most of their customer at any one time are usually holding listening to dreadful music or screaming at recorded automated voices in some form of menu loop. Its really bad. If you have a choice go elsewhere.
