National Highways Authority Of India [NHAI] — Abuse

Dear Sir,
I am an employee of Chennai Petroleum Corporation Limited, a Public Sector Undertaking. I use Mathur toll road for commuting between my residence and office. I get monthly pass for using the toll road. However, to my surprise the people who work in that particular toll plaza denied the monthly pass for no valid reason. When asked about it, all the toll plaza people gathered and abused with bad words. I am very hurt. Many people from my office faced such issues. It is my humble request to look into the issue seriously and advise the concerned to take necessary disciplinary action against those who are involved in this issue.
