HDFC Bank — fastag card

Address:

C-18, Sarvodaya Nagar , Behind Regency Hospital, Kanpur, Uttar Pradesh, 208005

Dear sir,
This is to bring to your kind notice that I, Anandeshwar Prasad was applying for Fastag card on the HDFC website Yesterday i.e. 27/11/2019. After completion of the form, I reached on the Payment page. When I have paid Rs.500/- by my credit card, my monitor has shown the following message and I received the SMS for deduction of Rs. 500/ from my card :
"Session time out or error on the page. Please try again after some time."

My car Registration No. is UP 78 AZ 7080. I have submitted Passport as my ID.
I have tried to contact your customer care number [protected] for at least 100 times but every time I found a busy message.
You are requested to look into the matter and do the needful so that I may be issued Fastag.
Thanking you.

Anandeshwar Prasad
