<prompt> Human: I recently had fraudulent charges on my credit card. So I called the credit card company to let them know I did not authorize a transaction at best buy for 450. They went down the list with me and asked me about my other charges all of which I said were mine. I remember distinctly they asked me, what about the REI charge for 340, and I said That was authorized, I made that charge. The only one that isnt mine is the best buy charge. So then they said ok Ill transfer you over to security to remove the best buy charge.Well I got my new card in the mail and saw that they removed the best buy charge AND the REI charge, and some 8 mcdonalds charge. I thought well maybe they will put it back.Then I got a letter in the mail saying these are the 3 charges we removed and marked as fraudulent. Checked today, they never added it back.1. If I call them and say mcdonalds and REI was mine. Will they add the charge back? 2. If I dont say anything, will I get in trouble? How would they find out? This was their error not mine. Ill most likely do 1, because my conscience is killing me, but Im curious about 2.  <response>: You call them and tell them that they made an error in removing all of the charges.
