HDFC Bank — fastag suspended/wallet freezed

Address:

Bangalore Urban, Karnataka, 560105

I have given complaint ragarding my fastag. Till now no response from the concerned authorities...
I have a fastag which is linked to HDFC bank. It shows the tag is suspended and wallet is freezed because this i am not able to use this.
I have raised the complaint at the toll free number many times but no use at all. Also its shows that the login for the same fastag is blocked. Not able to do anything.
I request HDFC bank to close my fastag account and return my balance amount.
