Why oh why?? Post office Hell!!

I am so mad right now..I take so much time and care in my work..Just to have the post office ruin it..I sent over 29.00 worth of stuff to a customer she got it and the envelope was all tore to shreds,all the bubble wrap and baggies gone,one thing broke ,one thing missing and one pair to a earring gone..I am so tired of my post office being so careless..They put her envelope and stuff in a clear bag that says we care are you kidding?? Here is the picture of envelope and bag this is how she received it..So over the post office!!! And they will hear it when I go in next time!!!
