Your work place seem to be in Haryana and thus governed by Punjab shops and establishment Act. Prima facie, under section 22 of the Act, your termination is illegal and without reasonable cause and though on allegation of non performance, it ought to have been proved through charges leveled against you. If it was termination simplicitor then even one month's pay had to to be given with reasonable cause. If challenged under this Act, you can be awarded two months wages. If you are covered under definition of workman then challenge it under ID Act wherein you can be reinstated with backwages depending in circumstances of case. After your resignation you were entitled to be relieved after one month in view of section 23 of the Shops Act.
