Your edit note was correct. My current situation is exactly like your previous one. Ditching IUP and paying new phone in full. After an hour on hold and 3rd time calling. "Agreements" department said that it was technically a pay in full purchase that is being paid off monthly to citizens and that cancellation just sends the prorated amount as a refund to the citizens loan. Thus decreasing my total pay off amount. Crazy how I had to pull teeth for that to happen though.
Thanks all for the assistance.
