Right now the OP is only guessing it’s the commission that is still out. As you read all the threads about refunds you see that nearly everyone has had their refunds come in “installments”. I got one refund where the amount corresponded to the taxes and fees, another where it was equal to airfare. The next installment didn’t match any amount I could figure. A month later came two more amounts but I was still short $330. It finally showed up a couple of weeks later and then the total amount was what I expected. This may happen to the OP as well. It’s a frustrating process.
