My internship was cut short and these people are not paying me my money! Can you help me?

The person above me hit the nail on the head. The whole point of the internship is to get real world job experience to help you get either a job offer, or have something to buff your resume with experience. You are possibly squandering your effort and all the good work you did. The way they handled it seems shady, but you most likely signed a contract that stated your termination date. Either way, end it on a positive note, visit the office, ask for your hours already worked to be paid, and leave on a positive note with good references.
