My Terrible Trip!!!

I'm writing this with tears in my eyes,my family and I came down here to Athens,in Greece  for a short vacation on our way from the hotel to the airport I noticed that my wallet was  missing including Credit card and other valuable items were missing from my lodge. We've been to the embassy and the Police to complain here but they're not helping issues at  all and our flight leaves in less than 19 hrs from now but we're having problems settling  the hotel bills and the hotel manager won't let us leave until we settle the bills,I'm  freaked out at the moment.I'm so scared and I need your help urgently.
