<prompt> Human: Apologies if this is the wrong sub.Like I do every month, I check all my activity on my Discover Card before paying the bill for the month. Today I found a 13 dollar charge for renting a locker at a hotel a little more than a week ago. The details said it was manually keyed in. Aside from getting a new card number and such, is there anything else I should do? The strange thing is that its only 13 dollars.Thanks.  <response>: Report unauthorized charge. Dispute it. If you didnt do it, this should be easy.
