Yes, I heard all about this.. Northwind Express double brokered everything that didn't go on their (one?) truck.. Factored it all through T-Pine who sent out POD's and invoices. Northwind Express scammed T-Pine pretty good.. And everyone else too.
FMCSA shows Northwind as still active...
My two cents...
If you owe T-Pine any money then send them a refund/credit invoice showing you paying yourself back the full amount and that might get their attention. And you can negotiate with Adam, his plate is full with a lot of this garbage, and the quicker the outcome, the better for whoever he is representing.. Then T-Pine might fight later but they don't have a leg to stand on.. Since they send fake documents to get paid by honest brokers..
