IRB Infrastructure — Charged double toll Mumbai Express way

I was on my back from my way to Mumbai from Pune. I was charged 203 at the Talegaon toll naka via fast tag. I did not have have balance on my fast tag at the Khalapur toll naka so had to pay in cash. The attendant asked me for Rs 203 instead of the regular toll of Rs 67. That's Rs 136 extra!!

My vehicle no is MH46P2785. Please provide me with a refund. Attached is the copy of the bill for your reference.
