You used a roll of negative film ... that's why the colors turn out normal. If you want cross processed result, you need to use slide film and then get it cross processed.
You can't cross process a developed roll of film unless you are talking about scanning them and do it in Photoshop (eeew!). 
This might be of help ...

You can cross process negatives too but I've not heard of any shop here doing it.
