HDFC Bank — hdfc fastag not received

Address:

560029

Hi.
I did my fastag application acknowledgement on dec 2018.
Till now i haven't got my fastag courier.

My application reference no. Is hrf095613

I had called customer care couple of times and they gave tracking id in that it shows delivered in bangalore address.
The customer care people are only saying we have raised a complaint we will get back to you. No one is responding.

Very poor service.

I'm still waiting to hear from them...
