advice on: dry cleaners

[mike@ec]

Can anyone give me advice on what to do..

My wife dropped off her Down filled Jacket (Parajumper) to get dry cleaned, cleaners inspected the jacket and looked at the cleaning label and said they can clean it no issues.

When my wife picked it up, it was wrapped in protective wrap on a hanger, upon un-wrapping the jacket at home we noticed white spots on the jacket, we brought the jacket back to the cleaners to inspect and they said they would take a closer look at it and try to remove the spots.

Well, they couldn't remove the spots after a week, and the cleaners suggested to tell my wife to contact the manufacture to tell them about this.

So any advice on what I should do..?
