I only wanted to pay what was available in my checking account. Last month I had the option to make a partial payment. the intent was to pay out of 2 separate accounts which I did last month. When unable to see this option, I cleared out the information like name, account number, routing number ,etc. to zero all out to see what the next step looked like. but when I did hit pay, the entire amount was paid ..even though all was cleared. now my account is overdrawn!
