National Highways Authority Of India [NHAI] — Airtel Fastag

Website:

Airtel Bank

Hi, I had Airtel Fastag on my vehicle. And it has balance also but still its not working and whenever i go to toll plaza it shows low balance.
Airtel people's are not responding to my mails with this issue and they are not resolving it due to which i have to pay double toll even though i am having fastag.
I have mailed them 4-5 times.
Request you to take strict action. If the service provider will not help us how citizens will follow fastag rules.
