Waste of time!

I am due for an upgrade this month seeing that my contract is expiring. I phoned the upgrade department, after explaining that I am only interested in a sim only contract for now they put me trough to another department. After explaining again they put me through to another department. After explaining again they put me through to another department.. The sixth time I was put trough I landed up in the upgrade department AGAIN. Were they told me AGAIN they had to put me trough to another department. So please do me a favour and switch my contract over to pay as you go until I can make arrangements with a network who is willing to help me to carry over my number. Because this service is beyond pathetic! !! Who knows through how many departments I'll have to go to arrange for that..
