Mike,
As outlined in our company return policy and in the email you received with the shipping label, we refunded you for the price of the part and did waive the restocking fee. However, the original shipping charge is not something that is refundable on a return. Also, the cost of the return shipping label was taken out of the refund amount as outlined in both the return policy on the website and reiterated in the RMA email you received with the return label.
Best Regards,
Jareth
