On yesterday's drive, I had to pass through a total of 5 toll booths. Except one, all else said Fastag didn't get detected or worked. I paid cash 4 out of 5 times. A little later I got mails saying Fastag was also deducted every single toll booth. So I ended up paying double.
ICICI Fastag Toll Free Number 1800-210-0104 doesn't work.
The chargeable number 1860-267-0104 also doesn't work. Both numbers say 'Call Failed'
