I currently am paying for an new Galaxy s7 monthly. I previously, before March, had a Note 4. I had removed the Jump insurance for the Note 4 as of summer 2016. I currently have Jump Insurance listed for $10.40 and $12.00 on my bill. I agreed to having Jump for the new s7. Also important, I have a Tab A8 tablet on the plan that never receive Jump insurance.

When you removed jump it was prorated and then you added it which was back dated it looks like. Contact T-Mobile and see if they will credit some of it.
