Pushing Rollei CR200

Mourning the great loss of Provia 400, I was hoping I could reach a middle ground of shooting Rollei CR 200 and pushing it one stop. I live in Germany now and this film type is easy to get and relatively inexpensive. So, I shot a roll at 400ISO, correctly metered in camera, and asked the lab to push it one stop. Imagine my DEEP disappointment when I got results like the one shown down below. The result isn't even in color, and the lack of contrast was not even CLOSE to being just ONE stop under. Does anyone have pushing experience with CR200 or words of wisdom when it comes to shooting this film? Or did I just experience a lab processing error?
