NVMS (National Vendor Management Systems) NVMS National Vendor Management Non payment of services rendered to NVMS Manassas Virginia

I have been working for NVMS since late June. When i started i was told there was a 2 month delay in getting paid then after that its weekly. Two months went by and i received 2 invoices showing me my check amount and still no check came. I complained and then i received two checks totalling $50. I kept receiving weekly invoices for my checks that were supposed to be coming. I have 5 invoices right now totalling $1200. I have emailed , called, left messages etc and nothing. My rep says she will let accounting know and i still hear nothing. I am reading a lot online about a lot of people never getting paid. This is terrible. What if i needed that to pay my mortgage or feed my kids? Something has to be done with this company. It is terrible the way they treat their employees.
