Query: very bad customer service

I got this router and it just worked for 1 day. After I spoke with the tech support, they have decided it was a defect product then transfer me to the customer service. Unfortunately, the customer rep told me that it is their policy to have me pay for the return postage. I found it shocking that belkin asks the customer to pay for their defect item. Very bad customer experience. For that, I won't buy any more Belkin products."Please Note: This is not a pre-paid label. You will need to apply postage when shipping your defective item to Belkin." Is it fair?
