Wyler,
I moved out of my MQ about the time JPA went live. Thought I might have the same problem getting the system to stop charging for it. I got the same run-around as to who was responsible for actioning the instruction within JPA to stop the payments. In the end my very helpful mini-Adj discovered that she was able to stop the payment herself. She took my word for it as to the date my occupancy ceased and it was all straight on the next payslip.
