Vista National LLC THEY DO NOT PAY Brentwood California

I was hired to do a closing for Viata National LLC on 3/29/17. The closing occurred on schedule and payment for this service still has not been remitted by Vista. I contacted them via telephone and spoke with Rick Greenblat and was told that he would personally make sure that the check was issued the next day by Chris. He would put the invoice on his desk, that was on May 9, 2017 @ 10:32 AM and still no check. I tried to reach the today, May 31, 2017 4 times but to no avail. The first three times I was disconnected and the fourth time I had to leave a message.
