IRB Infrastructure — Double Toll Collected in cash and FastTag on Mumbai Expressway

During our travel to Mumbai from Pune 01 Feb 2020, while scanning fast tag at Talegaon toll, there was some issue, So we paid in cash Rs. 270 complete toll upto Mumbai. At Khalapur toll plaza, upon display of toll receipt generated at Talegaon, additional amount of Rs 203/- has been deducted from fastag account as well.

If there is deduction from fastag and cash both, it means there is big fraud with the toll system, knowingly complete toll already collected for the vehicle. Post this incident on call to Emergency/Helpline contact No on the back of Toll receipt, they were responding in very roughly manner and telling me "Paisa gaya toh gaya". Please refund my amount to my FastTag account.
