Consumer Redressal

I got a new Tata Docomo Broadband Connection on 28th Sept 2013- User ID: 0200445139 Account No: 989414954 When I registered on their website, I received my first time login password, but it did not work and I have been having trouble resetting the same as the new password is not being delivered to my email nor my mobile. On resetting, i get an email which say your Password has been reset and pin is sent to your mobile. But I never received any Pin on my mobile. I called up the customer care multiple times but they were least bothered to help. They always asked me to email on 3030@tatatel.co.in. On emailing them, everytime I get the same reply to do a reset password. Still I never got my Pin. I even copied the appellate authority on emails, but no response. Now, they are asking me to go to their store. How can the people at the store reset my password if the technical guys at the backend are not able to do so. Please help me with this issue. I have been extremely frustrated by them.
