We as a pharmaceutical company selling medicines to one firm on credit basis. The firm was to make payment on monthly basis. After six months, the company could not clear the account, hence we decided to stop selling to it. The firm, in order to continue the existing arrangement, give three post dated cheques. Two cheques amounting to Rs. 500000/- were bounced due to insufficient of funds. Mean time, the firm obtained the pharmaceuticals approximately to the value of cheques. After getting information of bounce of his cheques, he started making payment in piecemeal manner that is 2 lacs against 3 lacs cheque and thereafter one lac in intervals of 20 days or month. Then he suddenly stopped payment of remaining dues which he took pharmaceuticals during the course of repayment of cheques. As on date, the firm owe to us around Rs 6 lacs.
Please suggest what action is taken by us to initiate criminal proceedings as the firm has deliberately decieved us by issuing post dated cheques and getting them bounced and making slow payment of small amount against the bounced cheques and simultaneously obtaining goods on false promise.
