National Highways Authority Of India [NHAI] — charged amount on non-fastag lane and fastag amount also got deducted

My name is deepak k v. I was traveling from palaghat to ernakulam on 27-jan-2020 and when i reached at paliyekkara toll plaza around 4:30 pm i entered into a line but unfortunately it was local pass/ cash lane and i realized only getting closer to the toll gate and because of traffic i couldn't change the line. When i asked they told i have to pay by cash. So i paid 75 rupees by cash and continued my journey. But after passing paliyekkara toll plaza in another 30 minutes i got message in my phone as 75 rs was deducted from my fastag. So i was double charged. As i have to reach home urgently i couldn't go back and check with them. Below are the details

I am living in kakkanad, ernakulam
The above incident was on 27-jan-2020 at 4:33 pm.
Vehicle details :
Vehicle number : kl-56-n-9738
Car model : renault kwid
Colour : planet grey
Used fastag from hdfc bank

I have uploaded the photo of receipt of toll paid by cash at 4:33 pm through no fastag gate and photo of amount deducted from fastag confirmation email. It should not deduct money from fastag as this lane was local pass/cash lane or they have to let the vehicle pass if the vehicle have fastag.
I need to get my extra paid money back
