Dear sir,
I am an asst prof at manipal university jaipur. I cross the thikariya toll plaza at jaipur ajmer expressway (Car no. Rj14cl0685). To avail the local benefit i have activated my fastag id (Wallet id[protected] with local toll.
Today morning the person at toll window told that my fastag is invalid and blacklisted. After a long discussion finally i gave him the exact amount of toll rs. 60/- and then he allowed me to cross the lane. After a few minutes i received a sms on my registered mobile number that "your fastag has been debited for rs. 15/- for transaction by vehicle rj14cl0685 on[protected] at 9:15 am".
Therefore i had to pay twice for one journey and also the money 4x than the normal.
On this thikariya toll plaza near bagru at jaipur ajmer expressway it happens 4-5 times in a month and they ask for full payment (Manually) by saying that the fastag is blacklisted.
Dear sir, this can not be accepted as it is clear that no one can charge twice for a single journey.
I therefore request you to kindly look into the matter and do needful.

Regards
