National Highways Authority Of India [NHAI] — traffic block at toll plaza

I was travelling towards ernakulam, kerala by nh544 on 11th may, 2019. We confronted a huge traffic block at paliyekkara toll plaza and we have been made to wait around 15mins. So i refused to pay the toll. On returning from ernakulam, we encountered another long queue at the same place, so i opted to move through fasttag lane. But, i have been blocked by showing "black listed" on the screen. We were made to wait more than 10mins, following that i refused to pay toll since the maximum waiting time is 2min 50sec, and i drove away. But, got a mail that a toll amount of rs 70 has been deducted from my fast tag account.

What is this sir!!

Is this justice!!

I am requesting a refund and an action against the toll collecting company.

Enclosing the screenshot of the mail intimating toll amount deduction..

Thanking you..
