Query: Logitech dosen't back there systems

Purchased my Logitech Z-5500 THX-Certified 5.1 Digital Surround Sound speaker System back in July of 2007 with my computer system. Sounded pretty good (bass isn't the best)but I could live with it. After two years I started to have problems with the pod and then the system stopped working. I went to the Logitech web site and they said the site was down. It finally started to work and I sent a e-mail to Logitech and told them what was going on and never got a response. I had a computer tech check them out and he couldn't figure it out. I will never buy anything from Logitech again. There is NO customer service.
