Rude agents and ******* contract fee increases

Your agents are rude and abrupt and when I ask to speak to a manager she drops the line!!!

How can you call people and say you migrating their contracts with no migration fees but then increase the monthly amount after you just added money to my contract without any communication.

What are you doing about your rude agent that doesn't escalate calls when asked too? And, how are you deciding what my contract fee and structure should be without my permission and approval???
