Arc Preservation not paying contractors Internet

Arc Preservation is normally a good company, but as of here lately you can't get paid from them.  And if you owe an advancement to them, it never seems to get paid off.  They hold more and more out of your check until they are keeping all of your check to pay off an advancement.  When you are doing almost $3000 worth of work, why is it that the advancement never gets paid off?  I am tired not getting paid to do my work.  I am tired of getting sent on bull crap orders of having to drive 6 hours for a $70 order.  You spend $150 to make $70.  I have lost more money from doing the orders than I am paid for the orders.  The amount you get paid from them keeps going down, when you do get paid.
