They recommended that I change the old pipes in my bathroom, I got them myself, and I hired them to install them, so they came and did their job, but some time later I decided to do an installation and when I broke the wall I realized that they were there the same old pipes, I called them and complained but they told me that I was confused, that the work was done, but the detail is that I know well the pipes that I got and although I never saw the old ones I know perfectly well that those are not them.
