If it's a focusing problem it will be sharp somewhere, either in the foreground or the background. From the sound of it this isn't the case, so it probably is a 'soft' lens.
We have talked about this before on this forum. The subject of Colimation, which is the fine adjustment of all the elements in the lens to bring the image to a sharp focus. Just because it's one of Canon's top-of-the-range lenses doesn't exclude the odd rogue getting through, although it would speak volumes for their quality control.
I think Jaime's done the right thing sending it back from whence it came. although we don't know where he bought it and how long he has been waiting for his refund.
The day you think you've found perfection is the day you stop looking, then someone else will find it and move in front of you.
