Mango Shopper Bag Leaves Permanent Water Stains After Cleaning

I purchased a Mango Shopper bag, and every time it comes into contact with water, stains appear on the surface. For example, when I return home and try to clean the bottom of the bag with a wet wipe for hygiene reasons, permanent marks are left on the areas that dry.

This issue makes the bag extremely difficult to use, and I am very disappointed with the quality. I have used nearly all of Mango’s shopper bags in the past, and none of them had this problem.

In the photos, it is clearly visible that the water stains change in shape and location each time, proving that this is a recurring defect in the material. I request that Mango resolve this issue, either through replacement, refund, or an alternative solution.
