App lacks functionality

Used this app to transfer money to a family member. Payment went through the well the first time. However, I was using the app to check bank account information and unintentionally sent another transaction on the way. I was unable to cancel the transaction within 2 minutes, then the app dialed out the customer service #. I have had to call 3+ times to get this resolved and nothing, I am so upset that this app does not have the ability to cancel requests. This is unacceptable, I cant check bank account information on the app, cancel, etc.
