National Highways Authority Of India [NHAI] — Fast Tag Lane not in operation

Address:

562111

Dear Sir,
I am daily user of NH4 and pass 2 Tolls twice a day. They are Navayuga Toll after Peenya and JAS Toll at Nelamangala. At both toll plaza's the Fast Tag does not operate properly. The sensors do not authorize gate opening even when there is sufficient balance in the fast tag account. Sometimes it opens and when you are about to pass it suddenly closes. This can cause serious injury to travelers. There seems to be a technical glitch which is unresolved for quite some time. Especially during evenings all vehicles are allowed in fast tag lanes making them useless.
It is very annoying considering that we deposit excess money in advance and still have to wait in long queue's.
I request the concerned authorities to take suitable action.
