National Highways Authority Of India [NHAI] — Improper Maintanence and Technical issues in while Reading Tags

30th October. Time between 4.15 and 4.40 Pm. Everyone please take kind attention, yesterday we travelled from Trichy to Karur . We have been waiting for more than 20mins in the Perugamani toll. As per the law if a vehicle is supposed to wait for more than 3 minutes we can get exemption to pass the toll. But they compulsorily collected toll fare for all the vehicles, which they waited even more than 30mins. And in the 2nd toll to Karur there are technical issues happening always. My tag has more than Rs400, but their device didn't deduct my tag and I have been asked to pay double charge, after showing the message from 1st toll only they manualy deducted balance from my tag. One more thing due to improper Maintanence still traffic is happening in toll. Vehicle no TN45BR2243
