HDFC Bank — not recd my fastag yet

Address:

G-3 SOURAV TOWERS, VAISHALI NAGAR, Jaipur, Rajasthan, 302021

I have recd a massage for fastag issue on 28/11/2019 transaction id is [protected] but i have not received my fastag yet I HAVE PAID RS 500/- and i have recd massage customer id but fastag is still not recd.
i had other options also to apply for fastag but i chose HDFC since i am their customer for very long time and satisfied with their services but this time i am high disappointed in this case worst part is that there is no way to track the status their helpline no. is helpless either its busy or not responding, now I have to travel out of station and i have no fastag even after applying such long time back
kindly look into matter and send Fastag ASAP.
