Yes. about ten years ago now I bought a bike that I realized was somewhat too large. Shop wouldn't take it back even though I called and asked the very next day. I was able to make the fit work, but was also happy when the frame became damaged and I had an excuse to toss it.

I don't know what advice to give you in your current situation. Are you able to test ride the same bike in the 47 mm size? Are you certain of the 47 mm size fitting you better?
