If you were charged multiple annual fees, it was likely because you first signed up for a small annual prepaid plan, and then later increased your plan size. We charged you one fee for the first plan, and then a second, prorated fee (taking into account your previous fees) for your increased plan size. If you saved and submitted a smaller plan and then a moment later resaved and submitted a larger plan, you will still see two separate charges on your bank account as our systems recognized those as two separate plans.
Please read here for how plan changes affect fees.
