Wrong address for Coldplay ticket

Hi, I bought the 25th Jan Ahmedabad tickets to coldplay and in hurry put the other address in Kerala instead of Delhi, where I am right now and from where I'll be going to Ahmedabad. Is there any way to get my address changed?

Another option is to get the tickets couriered to my friend who will be joining from Bangalore once they get delivered in Kerala. But that is risky as I do mot know when exactly would that happen. Is there an option to get the tickets on the date and venue of the event?

Any help would be greatly appreciated!
