U.S. Bancorp Credit Card Complaint

U.S. Bancorp Credit card department,

Other fee New York

- credit cards that I paid off in full sent me a bill for interest after I paid off the balance. I called both companies and both of them just simply reversed the charge ( much to easily, in my opinion ). While that is all well and good, I ca n't help but wonder, how many people just pay that bill? It seems to me that this is somehow fraudulent or at the least a very sneaky way of getting money from unsuspecting consumers.
