WCF - I Cant reach my Methods in my new Webservice

Question

I have made a simple WCF service, but I can't get in touch with the methods within the Service. It something to do with Cros Domain issues.

I have tried out selveral post and tutorials, but it simple wont work.

When I try to access CreateUser method, it returns a "Method not allowed"

In addition to above - The server is a remote server and I have access to the settings.

Ajax Post

    <script type="text/javascript">
    function createUser() {
        var user = {};
        user.Username = $("[id*=userName_input]").val();
        user.Password = $("[id*=userPass_input]").val();
        user.Country = $("[id*=userCountry_input]").val();
        user.Email = $("[id*=userEmail_input]").val();
        $.ajax({
            type: "POST",
            url: "[url]/AttService.svc/CreateUser",
            data: JSON.stringify(user),
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            processData: false,
            success: function (response) {
                alert("User has been added successfully.");
                window.location.reload();
            }
        });
        return false;
    }
</script>

Service

    namespace AttenttoWcfService
{
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    public class AttenttoService : IAttenttoService
    {
        [WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest)]
        public void CreateUser(User user)
        {
            SqlConnection con = new SqlConnection("Data Source=;Initial Catalog=Registration;User ID=xxx;Password=xxx");
            con.Open();
            SqlCommand cmd = new SqlCommand("insert into RegistrationTable(UserName,Password,Country,Email) values(@UserName,@Password,@Country,@Email)", con);
            cmd.Parameters.AddWithValue("@UserName", user.Username);
            cmd.Parameters.AddWithValue("@Password", user.Password);
            cmd.Parameters.AddWithValue("@Country", user.Country);
            cmd.Parameters.AddWithValue("@Email", user.Email);
            int result = cmd.ExecuteNonQuery();
        }

    }
}
