Query: Defective Amp

The ordering process was quick and easy. It was delivered within 3 days. Unfortunately I did not get to enjoy it for a day. After a few hours of using it, the internal amp blew. No output no matter what inputs I used and no matter how many times I recycled on/off. You can hear the speaker make a sound upon powering on but no sounds are produced. This is extremely disappointing. Just when it was sounding really good. The second issue was the ipod dock does not charge your ipod while using it. If you use RCA cables from Ipod to input side of speaker, the volume level is much lower. Now the worse part of this experience was I had to pay over $45.00 out of my pocket to send it back for a refund. How can I dare to risk buying again another product if I would have to pay shipping charges if it comes out defective?!Very unhappy with this experience!!!
