No service from Call Centre at all

I am at my wits send. I have been trying to cancel my 3G contract for over a month. Up to now my experience has been:<br> <br> 1) Contacted the Call center and their message says their call center is unavailable???? Really??<br> 2) Get through to an agent and they say they cannot do the cancellation but they transfer the call which doesn't get answered after 10 minutes<br> 3) Nobody can give me the number to contact directly
