National Highways Authority Of India [NHAI] — Not returning the change of 1 rupee

Address:

Chikkaballapur, Karnataka, 561207

Hi sir/madam,
I am staying in bangalore. Almost every weekend i go to my native (Anantapur) which is around 220 kms from bangalore.

The toll charges are recently increased to 85 in bangalore toll plaza and bagepalli toll plaza.
Usually we give 100 and expect 15 rupees to be given back.
The toll plaza guys give 14 rupees as 10 rupee note (1) and two rupees coins (2). When asked for another 1 rupee, they say thay have only 2 rupee coins. They are saying that they are being given only 2 rupee coins. From where we should get a 1 rupee coin everytime. Why can't they give rs. 5 coin. I started fighting with them everytime.
And it has become a routine for me and them. Every weekend when i go home this is the situation at these two tolls (Bangalore and bagepalli).

Please take an action on this. Enough of government and other eating our money in the form of taxes, toll fees etc..
Cannot afford to loose anything in this kind of #.

Thanks.
