Dahisar Toll Naka — Collecting toll by cash plus fastag.

On 24/02/2021passing through Dahisat toll towards Miraroad, asked to deduct toll through fastag. Person with hand held instrument scanned Fastag and told that their is no enough balance in my account and to pay by cash. I paid the cast by transaction number [protected] through lane number L01 and HAPPY JOURNEY at the end of receipt.
I also got message on my mobile about deduction of Rs. 40/- through HDFC.
This means your instrument is faulty, or your person is telling lies, or you have got a method to collect maximum toll.
Please guide me if any way is available to get refund.
I can produce toll receipt as well as SMS from HDFC.
