Call Centre or game of pinball?

I've been on the phone now for almost 3 hours, simply to subscribe to the doGaming promotion. After waiting 40 minutes to get to an operator at sales (makes sense surely) I am told that they need to transfer me to another department for my request. I wait over an hour to get through to the new department, being faults and billings. The guy there tells me, no they can not process this and must transfer me. After yet another 40 minute wait I get to a department, whose name I was not given and attempt yet again to make my request. The woman there listens and just says Ok, doesn't say another word and I am put back on hold into ANOTHER TRANSFER. Are you kidding me? Not only does the call center not know where I am supposed to go for such a simple request, but I must go back to the end of the queue each time! I don't have 4 hours to waste on this!
