West-Aircomm Federal Credit Union

I noticed my bank account wasn't showing a credit, so I went to deposit $40 in my checking. When I got there, I was informed I was charged a $30 courtesy fee. Upon review, I noticed I was charged this fee incorrectly, as I still had a positive balance in my account before being charged this fee. When I asked, they stated it was due to a pending charge. Yet, after both pending charges occurred (not to mention the $40 I deposited), I still would not be in the negative. I was treated horribly in front of my children and other customers by the ACH manager, who stated she would credit my account one time and also said, "If you kept a checkbook, you would see the charges." Which I do keep a checkbook, and that is how I know my account wouldn't be negative. I have been charged "courtesy fees" before, and I did not think to look this closely when they happened, so therefore, since West-Aircomm Federal Credit Union cannot be trusted, I am asking that any and all courtesy fees I have incurred be returned to me due to the fee I just incurred while still having a positive balance.
