1. A 26AS statement reflects the TDS deducted by the person making payment to the recipient
2. now TDS will be deducted from the payment being made only when the party paying has some debt or other liability towards the party receiving the payment
3. if that is so, then in my view, ofcourse the 26AS statement can be used by the creditor to show that amounts are due to him from the debtor party
4. as the payments to your company have been pending since April 2013, you can always say that the repayment terms were mutually extended by the parties orally from time to time. This is to get away from the bar of limitation so that your claim is not adjudged as a stale claim
5. the question whether the repayment terms were orally extended will be decided by NCLT at time of hearing based on the documents and materials placed before the court
6. you can also make use of the fact that in your books of account you had been showing the amount due to you from the company as an asset or receivable all throughout which would go to show that the loan is not written off and is still subsisting
