Citibank — renewed credit card from citibank not received

Address:

Mumbai City, Maharashtra, 400701

Since last few weeks i have been chasing citibank for sending me the renewed credit card to the changed address. But i neither get any response from them nor any revert.
I had a horrible (Unprofessional experience) dealing with citibank when i opted for suvidha account in 2010, and since then i had stopped interacting with citibank in anyway, but in shoppers stop i was assured best service for its mastercard citibank card with shoppers stop. Since then i am facing the issue. Now after changing the address, i still have to chase them and remind/followup countless times to send me the renewed credit card to the changed (New) address.
