Body Care — I'm complaining about vest design which got washed away

I had brought a vest for my 7year son which had some captain america design on it, unfortunately after 5-6 washes, the design got washed away which has never happened before. Just wanted to inform you about it and as we don't expect such thing from such a organized brand. Also from your vest the brand name is getting washed away. How can you all be so careless about it?
