Payza We've been waiting for our check since July 9th with no response to any support tickets , Internet

My husband and I are still waiting to receive a large check that has shown a status of completed since July 19. We have no way to track the funds or estimated time of arrival. Meanwhile, we have two other large checks tied up with Payza that were requested on July 16th and 23rd that still show pending status, despite the fact we received an autoresponder email stating that withdrawals after our initial verification on July 9th would be processed within 1-2 days. Our support tickets go unanswered and their customer service line goes unanswered each day. We are extremely concerned by Payza's lack of accountability, which doesn't bode well for our money. With the high fees they charge, you'd expect superior service. Apparently the fees aren't incentive enough for Payza to deliver our $11,500 as promised. I imagine the interest earned on what seems to be a high volume of delayed payments this month from our organization alone has been quite lucrative.
