National Highways Authority Of India [NHAI] — issue with fastag at kini toll plaza

Address:

411015

I traveled from pune to chennai via hyderabad on 23-24 oct (Vehicle no mh12kt0580) and returned from chennai to pune on 1-2 nov via lepakshi and davangere. The fastag worked good, though there are some delays because only one lane is fastag at some toll plazas (Need more gates for fastag). However, kini toll plaza made a problem because their fastag detector (Both the one overhead and the handheld device) were not working. But instead of accepting their fault, they said that my fastag has been blacklisted. When i said that i used it all the way for almost 2300 km, they said that my balance may be over. I showed him that i had 950 rs balance. Finally i did not agree to anything and forced them to use the handheld device again. This time it worked. This is totally unprofessional on their part. What will happen when all the vehicles have fastag in the future?
