National Highways Authority Of India [NHAI] — Toll Tax Penalty Regarding

I was traveling from Jaipur to Sikar.. When I reached at Akhepura Toll Plaza on NH-52, I went for cash payment window reasonbeing I have FastTag however, due to non-availability of Internet for past 3-4 days in Rajasthan and still today I was not able to recharge the FastTag.. Without prejudice to the above, Though I went for cash payment window, I have been charged penalty of Rs.65 totalling to Rs.130 for Blacklist of Fast Tag? ..

In this regard, it is kindly requested to tell me that what has been done with me is right or wrong?
