Let me route you to the best support available to explain the charges you received.
For us to know when the charges started, we'd need to pull up your account. Here in the Community, we're unable to pull up your account.
I suggest you contact our Merchant Services team. This way, they can securely pull up your account and provide you with the details about the charge you received. Also, they would be able to help you with other concerns about your merchant account.
Please let me know if you have other QuickBooks concerns.
