BrokerPriceOpinion.com review: Nonpayment of valuation work

30 unpaid broker price opinion jobs, between June 2014 and February 2015. All were submitted timely and approved by quality control. They owe my company a total of $1, 540.00. I began rejecting their orders in February due to nonpayment. They repeatedly advise me that we are scheduled for payment, but we receive nothing.
