Pierre Cardin Suit Rapidly Fades

Hey! I just bought a suit for men from the Pierre Cardin store. The price was 14,999 Turkish Lira. I wore the pants once and washed them at 30 degrees. But then I realized there were some serious problems with them. There's some fuzziness around the belt area and the belt loops. You can see sewing marks on the fabric of the pants, especially. Problems with sewing in other areas. Shortening the length of the pants. Basically, the pants became completely unwearable. (Check out the images I've included.) When I talked to the store, they told me that I should have looked for these problems because they exist in all of their clothes. I don't understand why a suit, which is made to keep you safe from the outside elements, is called "water-resistant." Doesn't rainwater or accidentally getting splashed in a puddle ruin your clothes? They think it's our fault for getting wet in the rain. The company and the seller have been completely unhelpful up until now - no solutions, no phone calls, no responses.
