Allocating contract under false pretenses

Work was alocated to my compact by Nigel Leighton. He alleged it was part of a Broleigh in Store solutions contract. After copletion of the job hé said My company must invoice for payment. After mailing the invoice hé said i suppose to invoice his company Broleigh instore steel. I did invoice and he is reddingen to pay. Hé has de*****ed my company and they are not thrustworthy. My company is not doing any business dealings with them. Genuine ******.
