Refund Request Not Entirely Fulfilled.

I am extremely disappointed with the service of Levi's Online, it's been almost three weeks since I returned two of my orders back only to get a credit of one of the Jeans I purchased online and the money for the other order which has two jeans has not been credited back to me, I've since sent emails to the support team with no response, I am frustrated and would like to have this resolved as I want to purchase new jeans with that money, can I get assistance please.
