I was charged $77.50 today under the name of Cornerstone! When I called my bank to find out where this came from, they told me it is a company named Sage/Cornerstone. Tim is looking into it.
It's the end of the month so it's most likely your credit card fees for the months, but that's just a guess.
Credit card fee would have been $12 and it is charged at the beginning of the month. So, it is not that.
The money was credited back to my account.
