HDFC Bank — I didn't receive my welcome kit and not able

I opened my account on 24th july from nagaon branch hdfc bank. It's been over a month and i still didn't receive my welcome kit. I went to your branch and they were didn't help me at all they just said me that it will come. I asked them for my welcome kit so they just gave me my tracking number and said that it's not our job to get your kit. They also filled wrong email id during registration. I asked them to change it and they filled for it but its been 4 weeks and my email has not been changed. They said that they filled for it and it is not uploaded in the system. It has been 4 weeks since they filled for it. So i cannot even use online banking.
