HDFC Bank — regarding my credit card

I got a msz stating my credit card delivery is done by Blue dart.but they didn't due to address related issues.
I had actually given my postal address and I still stay there.i gave even my office address but as it is shifting in amonth I asked them to post it to my residential address which didn't happen
And I seriously don't understand y does u customer care numbers don't work.they again ask to check the website.no phone banking officer speaks on the given number .whom should we report
