I know a company that were owed over 1.2 million by Carrillion. Like you said, later and later payments. Threats of taking them to court resulted in threats from Carrillion of no more work from them. They never received the money owed either...Carillion cost me my business and 63 employees their jobs. Owed me multiple 6 figures and payments always late or short. Then they just decided not to pay anymore. Feckers!!!!
