IRB Infrastructure — Toll during heavy traffic

Dear Sir/ Madam,
As per my understanding, Expressway Toll is charged as this facility saves our travel time and fuel. I was travelling by my vehicle MH06BM9110 from Mumbai to Pune on 26/01/2024 at 13.45 hrs onwards. There was heavy traffic on the expressway at Khalapur toll plaza and beyond. It has not saved my time as well as fuel though I have charged for Rs. 240 at Khalapur toll plaza and Rs. 80 at Talegaon toll plaza.
You are requested to give proper justification for charging a toll to my vehicle in heavy traffic, else please refund the amount.
