[Resolved]  HDFC Bank — Account blocked due to address change letter undelivered

I created a salary account in hdfc online. But i have to visit many times to branch. First time I have to go for completing kyc as they were not able to complete online. Second time they said again to visit branch that my kyc is incomplete. i go again and complete kyc and also i receive my debit card, passbook, and check book. After they again call me and said to go to branch because my address is not match with the adhar card. I go again and give me my adhar card and after few days I got message "Account blocked due to address change letter undelivered". I mail to them they replied with a link and said to update address. I follow the steps and got a message that my address change request is successful. But my account is still blocked. I mailed them about this too and waiting for responce. Why I have to visit branch all the for their mistake.
