National Highways Authority Of India [NHAI] — dasna toll tax

Address:

Ghaziabad, Uttar Pradesh, 201015

Why this toll is taken by the authority when highway is under construction and their is so much traffic jam on road. The toll employes were misbehaving and abusing the vehicle owner. Is this is the right way to collect the toll.
On every weekend i am travelling on this road face a lot of problem. Till the highway is under construction the toll will be not taken by the authorities.
My vehicle number is up16br7698.
