Amzn Mktp Us*ma6Es8Zu2 Amzn.com/bill Wa — charges made on my charge card that i did not make or especially authorize

There was a charge submitted to my card on the 22nd of july (07/22/19) from the above stated amazon entity for thirty two dollars and eighty-nine cents. I did not authorize and was not aware of any such transaction. My card company has been informed and advised me to contact you to correct the matter, please reverse these charges asap. There is no mistake about this erroneous charge it was my wife's birthday and no cards were used because we had just returned home from her mothers funeral, i have no other information except that which was stated and the unauthorized charge of $32.98 to my mastercard from amzn mktp us*ma6es8zu2 amzn.com/bill wa
