There is a vast difference between a corporate TA contracted to your employer to provide a service and an opaque third-party vendor such as PL. This entire thread has nothing to do with the former type and I don't think that we should confuse the two.
OP paid his money to PL and he will need to get his money back from PL. I agree that getting his CC issuer involved may be the best and fastest way to go about this. As he is based in the US and is flying from the US, I will presume that he has a US CC. He ought to be able to initiate a chargeback dispute. If he is correct on the facts, he ought to see his money in short order.
One messy issue. PL may see this differently and cancel his other tickets.
