HDFC Bank — HDFC Fastag KYC Issue

Dear Team,

I purchased my car in Feb 2019. The showroom provided HDFC Fastag by default in my car. Fastag is working fine till Feb 2021 and suddenly I was unable to recharge my wallet due to an incomplete KYC update. Without proper communication, they blocked my wallet.
Even I send my KYC details to the customer care number. but to date it is in not updated.
Even showroom JSP Ford Hosur road people have not informed me about the update of KYC.

With regards,
Naveen.
