I was actually thinking exactly what MotownJ is suggesting because if it does come back to you having put through a bad charge, your employer might have issues with you whether you say anything or not.......so if you can make the credit & return the money to the company for the credit....you would be being the most honest & have the least amount of harm.

Would think that the company you work for would wonder where the money went to that was charged because it should be in their account & would be missing from your employers accounting.
