Remember just because CO generates a refund transaction does not mean the CC company posts it that very moment. A CC company can take up to 30 days before it posts a credit transaction. This is because of the way CC transactions are handled. When you make a purchase it only generates an authorization. A few days later the actual transaction posts. The same is true with credits other then the fact an auth. is not required. I used to work in retail and had customers mad all the time that the bank hadn't posted the credit. We generated the transaction and sent it with the next batch of transactions, after that it's up to the bank.
