Fastag — my fastag showing blacklisted but it has rs90 balance

Address:

DLF VALLEY PANCHKULA, Panchkula, Haryana, 134107

Vehicle no. Ch01au8251 crossed today chandimandir panchkula toll plaza today 22.01.2020 in evening around 7.45pm. My fastag was blacklisted in their machine though it has balance of rs90 at that point of time but they didnt listen to me and charged double the amount rs 60 without my any fault.
Whats the use of fastag if i have to wait and pay double amount even after having sufficient balance in my fastag account.
