Not able to utilise credit for cancelled ticket. Review on SpiceJet

I had cancelled a Spicejet ticket about two months ago and have an amount of Rs 1775 is to my credit.

Today I wanted to utilise the credit amount to book a ticket. Spicejet website is not accepting the canceled PNR which is required to utilise the credit amount. Their reservation numbers 18001803333 and 098718033 are not available. **I tried both the numbers AT LEAST TEN times each. The first number is dead. For the second number I got recorded message 'Please check the number you have dialed'.

I sent mail to custrelations@spicejet.com

Immediately I have received an automated reply:
