I used the same url to download iso and installed it.
I called MS customer care and they are asking me to wait for 24 -48 hours to get activated
Did you do an upgrade install? In that case it should have been activated automatically once you connect to internet. If you made a full clean install then you need to provide product key which you will get after upgrading to Windows 10 using key getting tool e.g. PID checker or magical jellybean key finder.
