The correct answer is that a company should call the General Services Administration.
The General Services Administration (GSA) is an independent agency of the government of the United States, created in 1949 to help control and support the basic operation of federal agencies.
GSA provides products and communications for US government offices, provides transportation and office space for federal employees, and develops cost minimization policies and other management tasks throughout the government. In addition, it is the government agency responsible for payments to government contractors.
