National Highways Authority Of India [NHAI] — deducting twice the amount

Few days back people from nawabganj (Unnao) toll said machine not working, we took the return journey ticket but while returning i got message rs. 70 charged and same happened today, why to waste money i am not going to recharge this again. Nhai must look into this whats the use of such services we are cheated

Thrice i have noticed such mistakes even great amount of collection government is making by cheating public.
