Yes, they were horrible to deal with. We did a load for them and after we submitted clean POD they stopped answering our calls for about a month or 6 weeks.
Then their dispatcher was very rude to us when we reached to them after 90 days outstanding. I said I was going to call his customer for payment and replied "if you do that then I will outright not pay you". So I called their customer detailing my experiences with them and let them know I'd be coming after them under the bill of lading act, they called J-Dub and we ended up receiving payment after 105ish days out. Absolutely horrible, unprofessional company to deal with.
