National Highways Authority Of India [NHAI] — Technical glitch in fastag system at Attibele toll

I am a regular commuter through Athibele toll plaza. Recently almost everyday there is heavy jam in toll both which occupy most of our travel time. The reason improper scanning of fasttag. Most of the scanners are not working, so they use bamboo stick to scan fast tag. Some ladies staff with less hieght is finding difficulty to scan as well. I am not sure why those problamatic scanners are not replaced and why bamboo stick jugad is using with good technology like fasttag. Request concerned person to do the needful and resolve it.
