National Highways Authority Of India [NHAI] — Toll exemption for army personnel

Journey from Ambala to Pune-
The toll counter at mahendergarh on NH152 stopped me 45 mins for taking money where the supreme court order says that serving officers are exempted from paying toll even while travelling in personal vehicle. Also they did not understand the basic english in letter to decode that we are exempted with the exemption pass yet the officials denied to accept it when explained.
