HDFC Bank — fastag not received application reference no hr[protected]

Dear Team,
My Fast tag for application reference no HR[protected] is not delivered yet. It was applied 11 days back and there was commitment to deliver it within 7 days.
However, fast tag customer id and wallet id is issued on 29.12.2010.
Cust id[protected]. Wallet id - [protected].

Still its disappointing that fast tag is not delivered and also there is no tracking process of status. Also your toll free number always not reachable. I am not able to resolve this as I am unable to connect with anyone. Please look in to this otherwise please close my account and refund my all amount Rs.500.
