National Highways Authority Of India [NHAI] — Toll collected contrary to regulations

Sir
I travelled from jammu to amritsar on 13.07.17. The staff at toll plaza on pathankot to amritsar road on amritsar side collected toll of rs 85.00 from me. This was done inspite of my repeated requests that armed force personnel even in their private vehicles are exempted from paying toll. But all my requests fell to deaf ears of irb staff which manages that toll plaza.
Requested to do the needful.

Regards
