Common questions about this charge
Is the OPEN SOURCE TRAINING L charge legitimate or fraud?
OPEN SOURCE TRAINING L is a recognized billing descriptor. That identification tells you who the charge is from — it cannot by itself confirm that your specific transaction was authorized. If you don't recognize it, first check whether someone who shares your card made the purchase, then contact the merchant directly before disputing the charge with your bank.
