This is quite common. It also happens when you run your own merchant accounts. You issue a refund, but around the same time the user also request the money back at the bank directly and you get hit with a chargeback as well. In addition as a merchant you also have to pay the chargeback fee. So if it happens with a $30 transaction you are down like $-60 (plus processing percentage and gateway fees etc.). It's just one of the risks for doing online business.
The money does not go back to the customer twice, the merchant's bank is the one making the money here.
