WD3 - pipe broken after one month's use.

I bought a WD3 1 month ago. Just found that the pipe is full of holes, on several places. Looks like it melted?? It is the middle of summer, no heaters, no fires etc in the house? Though I think it is a good vacuum cleaner, the quality of the pipe is quite shocking. It basically collapses if sqeezed lightly. Compared to my old WAP's pipe it is truely poor quality. No point in saving on the pipe and making the plastic too thin if it is supposed to be a top notch machine. Check the pipe before buying. Maybe I should have stayed with WAP.
