Address:	Jaipur, Rajasthan, 302021
Website:	HDFC FASTTAG

Dear sir,
Recently i purchased a nexa car ignis registration number rj 14 zc 1202. I was given a fastag of hdfc bank number[protected]. The same was activated on 19 feb 2018 by the dealer and on the same day i charged my account with rs 500 with the help of my pnb credit card.
I traveled to ajmer on 16 feb and i returned to jaipur on 17 feb 2018 when my card was not even activated.
I received a message on 26 feb that my account has been debited as under
1, on 16 feb 2018 at jaipur toll plaza (Manoharpura 9002) at 11.37 am rs 60
2. On 16 feb 2018 at gegal toll plaza 6001 at 12.49 pm rs 265
3, on 17 feb 2018 at kishangarh plaza 8002 at 3.15 pm rs 35
4. On 17 feb 2018 at jaipur manoharpura 9002 toll plaza at 4.25 pm rs 340
It is not understood as to when the card was not activated how toll tax was debited?
When the card was credited with rs 500 then how rs 700 have been deducted?
You are requested to please refund the entire amount at the earliest.
