National Highways Authority Of India [NHAI] — I am complaining about deduction of amount from fastag within 24 hours return journey

Dear Sir/Madam
I have traveled through Sullurupet TOLL gate on 1st Dec 2019 at 19:45 Hours
my fastag has deducted Rs.60 and again after 15 minutes I have returned back through the same TOLL GATE., again Rs.60, so over all total Rs.120 deducted within a span of 15 to 20 mins.
Hence I request to take my complaint and return Rs.30 as for two way journey it is Rs.90 if we take the toll ticket manually, now it is automatic and deducted Rs.120.
go through my case and change the deducting rules as per present existing method i.e within 24 hours it has to deduct only 150% instead of 200%
thank you
