Maple Dry Cleaners

So I brought my very expensive moose knuckle jacket to this dry cleaners. I keep this jacket it prestine condition and I haven't worn it since last winter. So when I went to go pick it up the was black splatter marks all over the back of it. They had told me that it was already there when I know forsure they were not. They ruined my jacket and and tried to hide that they ruined it . I would never go back here in my life. This is ridiculous.
