@Glenn Carey, same with me.
I feel everyones frustration, after 1 week of battling with O2 reps i've finally got it fixed.
*So here's my frustrating and very long winded story with the incompetent O2 workers:*
The 1st time i called O2 iPhone Support, he told me to turn off 'Call Waiting' and that it would fix the problem, it didn't.
Called the 2nd time and spoke to someone else, she told me it was most likely a handset fault, and to go into an O2 store for them to look at my phone.
So went into an O2 store today, none of the workers even knew what the term 'Call Merging' was, the store assistant even had to ask me 'what was it called again?!'. He called O2 Technical Support, then told me i had to call 2244 'O2 Group Chat Information Line' which would sort my problem???
That was complete poo, cuz I then got told on 2244 that i had called the wrong number as I have an iPhone, that i needed to ring O2 iPhone Support which is what i did in the very beginning!!
So i called O2 iPhone Support and this time I talk to someone I mustn't have spoken to before, they do some investigation into my account and ring some other departments, and figure out that because my account is on the NEW TARIFF (600 mins + 500 txts) conference calling had not been activated on it yet- and this may be the same with other people's iPhone accounts. So he put in a request for conference calling to be reactivated on my account, and within an hour the feature was working. This guy knew what he was doing clearly, unlike the other reps
*Basically, I blame O2 reps incompetents on their use of knowledge based systems and how they are trained to go about solving things, very frustrating, where they only know how to troubleshoot using a step-by-step guide and procedures, and not to think outside of the box! If they did think about the problem more logically, a rep earlier on in my case may have brought up the possibility of the 'new tariffs' being the issue (that had recently been implemented) and needing conference calling on the new tariffs to be reactivated.*
