AC Adapter for E1705

My laptop is about 18 months old and I have an extended warranty.  A few months ago it started giving me intermittent problems saying that AC power cord was not compatible with the system.  I bought the power cord with the system from Dell.  When i pushed the cord into the laptop and would restart the system it worked just fine but it keeps doing this once in a while.  Today I discovered that the end that plugs into the laptop is frayed and coming apart.  I then went to buy the part on the Dell site and read many complaints that were similar to mine.  The part is under warranty for a year and in many cases people had to replace it under a year.

My question is does anyone know who we can complain to about this?  Why would Dell keep selling a defective part if there are so many customer complaints on the product's webpage?  This is totally unacceptable.  I have taken very good care of my laptop and I wouldn't expect a part like this to fall apart the way it has.  I am calling Customer Care on Monday because all I get on the weekend is customer service in India! All they could tell me was to take care of my parts...grrr.

If anyone has any suggestions on whom I talk to so that Dell starts paying some attention to their defective parts I would sure appreciate it.

Regards
