[Playing a slot machine which is restricted in Australia]

I joined Omni slots yesterday.  I deposited 3.2k into the one slot machine in series of $200 sums. 16 x in all.  The slot was not paying out at all. I think I had revived one free spin throughout depositing the whole sum.  
Then on my 17x that I had deposited I went to play the same machine but a message popped on my screen saying that this slot was not available for use as it is restricted in my country.   Where do I stand with this???.  I feel like the slot was not paying out at all and I found the slot is restricted.  If it was restricted why is it letting me play.
