thanks for the help.
My google index has now both the pages , new and old but the link in the search results still shows the old link. However only yesterday I have added to my htaccess file the following

RewriteEngine On

RewriteCond %{HTTP_HOST} ^friendsenggcorp.com [NC]
RewriteRule ^(.*)$ http://www.friendsenggcorp.com/$1 [L,R=301]

please help me if this is the right one or I have to change it
