Is it best to contact my bank or the credit card company about an unknown bill? - best bank credit card

Appropriations Bill. The problem is that I activated my new card with the bank, but forgot to add pay your account online. This bill is known, mysterious. I'm about 20% in April, doubling the funding in the amount of $ 1, and no annual fee. This is a new card. Thank you ask me again.
