KAYALAMI FOOD*****S DO NOT PAY VENDOR ACCOUNTS

We are a family business supplying beef to KAYALAMI FOOD *****S. They have outstanding accounts with us since May. Every time we call they promise to pay us and do not. CHARLES has promised to pay me on two occasions. The last was on last Thursday when he promised to pay on Friday. This did not happen. We have called again this week and still no payment. Are there any other suppliers not being paid by these people?
