National Highways Authority Of India [NHAI] — The fastag scanner couldn't scan the fastag pasted on car, charged double amount on cash

There was some issue with the fastag pasted on my car. The fastag was active with 2000 amount within it. It is paytm fastag on chassis no. MZBEU812TLN121733. I can't get another fastag for my car because one is already registered on this number. I am stuck in this loop. That fastag was not readable at the toll plaza of Palwal EPE. They charged us double the amount (INR 450/-). But it was not my fault that my fastag is not readable despite being in active mode. I am so disappointed with this behaviour of the toll plaza employees and the person I talked on toll free number 1033. Why am I being paid for the issue that is no way my fault? NHAI should come up with the solution without harassing the passengers!
