On Friday, XXXX XXXX, I logged in to my Bank of America Mobile Banking app to check my balance. A XXXX transaction had posted earlier in the day, leaving my account with a negative balance of - {$3.00}. I had {$4.00} transferred to the account to re-establish a positive balance. Later in the day, unbeknownst to me, another transaction posted ( perhaps a tip at a restaurant? But I really have no I idea ) leaving me with a negative balance of - {$2.00}. I was not notified that my account had overdrafted, and I did not discover this until XXXX on XXXX XXXX, too late to put {$2.00} in my account. I was provided with no notice of the overdraft, even though the Bank claims to provide courtesy balance alerts of their own initiative. So, I was charged a {$35.00} overdraft fee. I called customer service, where I was treated rudely and impersonally. I asked for a refund on the fee, which they did not provide, even though I acted in good faith to maintain a positive balance. It has been my experience that transactions with Bank of America post after XXXX, and I am confused about the timing of this transaction, and upset that I was charged the fee, when I could have easily funded the account had I been notified of the situation.
