National Highways Authority Of India [NHAI] — Fastag device at Simliya Toll Plaza

Simliya Toll Plaza in Rajasthan on NH-27 between Kota and Baran district tries to collect toll in cash most of the time citing problem with Fastag receiver.
I have travelled from Delhi to Baran multiple times on various national highways but rarely faced an issue with Fastag on other toll Plaza. But at Simliya Toll Plaza it doesn't work more than 70% of the time not just for me but for others as well.
