Credit card companies process enormous numbers of transactions and fraud claims, and their systems and investigators are not infallible.
A company may decide that charges were authorized based on information that sounds impressive—transaction records, merchant information, device data, or other technical evidence. But the real question remains whether that evidence actually proves you made or authorized the purchases.
If the company's explanation does not fit what happened, you are allowed to question it.
