Old website still showing up in Google searches with an added homestead extension to domain name

Dear Homestead: Please fix the following. I purchase my domain name from Homestead, but chose to rework my site once Homestead did not support Windows 8, and other features I preferred. I have had a new beautiful site for more than a year (goddessofgrants.com), but for some reason an old cached site shows up in Google searches (goddessofgrants.homestead.com), Please delete this. My guess is I am not the only customer who is experiencing this. Thank you!
