I'm sorry to hear that, did you requested a vacuum test ? this will prove who is at fault.

as you can see personal info should keep off the forum, but again a vacuum test will prove who is at fault, if it was the user or physical damage caused by the user which include wear and tear, or if its a factory issue.
