India Post — Revenue stamp not available in wakad pune

Address: Pune, Maharashtra, 411057

Hi,
I wanted to submit my House rent declaration in our office website for which I needed revenue stamp, I checked in all provision stores in Wakad (Pune) however no one had one. I then thought to go Hinjawadi Phase 1 Post office which is near to Persistent company however they had put a notice in front of counter "Revenue Stamp out of stock". When asked it was told to me to check with any provision store as they are out of stock from last 2 months. Is it so difficult to get Revenue stamp of Rs.1 ? Request you to please get this checked, just to ensure that people like me are not finding difficulty in searching for revenue stamp.
