Global Cash Card Money stolen and they wont return it , Internet

I have an account with global cash card. My walmart.com account that has this card # saved to it was hacked and I had 138.01 stolen from me. I called global cash card on 2/24/2013 as soon as I noticed this money missing and was told to fill out some forms and fax them in which I did. I was then told I needed a police report which I also filled. My wife had to go to the police department since I work and fill all of this out and when she did I faxed it in and was told they are denying my claim since my wifes name was on the police report. They will not return calls or my money although the card agreement says you are not responsible for any unauthorized charges. This company is a joke
