Dahisar Toll Naka — Collecting toll in cash + Fastag

On 24/02/2021 while crossing Dahisar Toll from Mumbai to Mira Road, I asked to scan Fastag for toll. Person scanned and said that their is no balance in my Fastag account and asked to pay by cash. I paid the cash through transcation number [protected] via lane no. L01. At the same time I gat message from HDFC for deducting Rs. 40/- .
This means they have collected toll for 2 times for single journey.
I can produce Toll receipt and SMS from bank as a proof.
