debenture

One of our clients ( Pvt. Ltd. Co.) had some debentures of Rs. 20,000 which were reedemable on 30.6.2008.
It re-issued those debentures as on 1.7.2008 for another 17.5 months without any new document or proof ?
What should have the above co. done to re-issue the same debentures again or how do i check the same?
And what are the provisions of COs Act that it has violated ?
