HDFC Bank — fastag not delivered

Address:

530045

I have applied for the fastag on 1/12/2019 and received a message with application number hfr821685, but the tag haven’t got delivered even after receiving the wallet i’d and customer id on 6/12/19. And there is no update from the bank regarding the delivery. And no one responds on customer care. At least they have to give the customer the correct information while applying for the fastag
