HDFC Bank — I did not receive the fastag

Address:

500070

I applied for the for the fastag on 08/12/19. For my heavy vehicle class 12 through hdfc portal. I have paid Rs.1100/- for the fastag. On that day they mentioned that we will receive the fastag within 7 days.
Till now no response from the HDFC bank side and one more worst thing is Customer care number is not working. This is the worst experience.
My fastag reference number: HFR954501
