A disaster, they sold me something that didn't work, I asked for the change and they reluctantly questioned me saying that the problem was my product. When I see all this I ask for the return of the silver, which they said no, after discussing that it was my right they tell me that it could be done but to all this I ate a mistreatment by the two sellers. I don't know they deserve a purchase. Not only do they sell you badly but they discuss everything for a product they sell defective. A shame, it was simpler to return the money and that's it. And not having to eat all the abuse. A little respect and nothing more.
