Our company has done several jobs for NBS. They required their contractors to sumbmitt a lot of paperwork with store stamps ect as well as REQUIRE you mail the origionals. They also were taking 2 + months to pay. Now after calling to inquire about past due payments and being assured it was all sumbmitted and being processed they do not answer the phone.

This will not be forgoten!!! read full review »
