Charged 3 times for the same game

I bought GTA San Andreas the other day. First time the order was cancelled for whatever reason and I see that refund in my account, I then tried to re purchase the game with success only to be charged 3 seperate times, so twice more than I should have??
These extra transactions are cleared, they are not pending..

I opened a refund ticket with MS but only got a generic reply denying the request and stating some policy where you can get only a cirtain number of refunds a year, of which I have had none.

Can anybody shed some light on this, I am just going to need to cop it. I am a bit hesitant to buy anything through the MS store if I need to pay triple.

Thanks
