National Highways Authority Of India [NHAI] — Wrong toll tax deduction

I travel from KMP expressway from Manesar to Asodha regularly from last 2 months for work.its charge is 120 Rs for return journey.But From Last 6 days there is deduction of 120 at asodha toll and 80 at manesar. On inquiry. I was told that i there is no record of my entry on highway. How is that possible that i enter on a highway without entry.everytime toll boomer opened with my fast tag. There is some problem at manesar entrance. Because during these over changing. My entry was not recorded at manesar. I also called 1033. But this numner is not working. Please look into this matter. As i am getting overchanged daily. I asked toll people if my car fast tag is registered properly at entrance and they say yes. But still i am getting fined.
