Overstock.com Informative - GET A MANAGER on the phone
I just received a refund that was $34 short due to the product being "non-restockable" The product was sent back in the same condition I received it. I called and was given the runaround by the first person I got on the phone. When she told me all she could do was give me a $20 store credit I asked to speak to a manager. Talyn got on the phone and quickly gave me my $34 refund. He even sent me an e-mail to confirm it.
Do not give up or let the first person you talk to give you less then you want. BE PERSISTENT!!!!
