due for upgrade and again its like pulling teeth

I am due for upgrade on 3 lines now as its just such a mission to do this. When i call i get the whole city run around and have to end up calling everyone for 1 single upgrade. all i get is ref numbers in my email that someone will assist but this is false hope. How can one do an online/telephone upgrade without going through the 3rd degree. I have once again been battling for over a week to upgrade at least 1 single line.
