This parallels making complaints, be nice but assertive to assure your point is not lost whilst not being a dickhead. The manager etc will be more inclined to give you free shit.
Further more, to get out of shitty contracts and etc once again be a gentleman, ask to speak to superiors and tell them that you were unaware/whatever. Tell them you're moving state and that their service has been amazing and you want to stay with the company (they'd much rather keep you than get a once off payment). Obviously bail and join another company once they let you go.
