National Highways Authority Of India [NHAI] — jam at fastag lanes in dankuni toll plaza

Address:

712102

Sir,
We were assured of seamless travel through toll plazas and hence availed fastag. I had twice passed through the dankuni toll plaza on durgapur expressway in the last month, and there were 3 fastag lanes, all jammed by trucks and availing manual toll collection on both occassions. If this be the scenario, can i be explained, as to why i was encouraged to buy fastag for my vehicle?
I hope, my complaint will reach the right ears, and necessary action taken.
