National Highways Authority Of India [NHAI] — charged twice in a single day

Address:

625020

Sir/madam

Vehicle no: tn91c 5254. I have taken fastag facility from hdfc bank for crossing toll plaza for hasle free movement, normally when we cross a toll plaza and come back in 24 hours we are supposed to be charged for double fee which is slighlt lesser than single toll fee.

I used a toll plaza on 29th of oct 2017 which is between mdurai and melur and came back in the same day.. But i was charged twice the amount of single toll which is 75 rs two times instead of double charge.

Also to mention i was asked to wait for more than 5 minutes as their fastag sensor was not working.

Pls advice how to resolve this issue.

Regards
