Query: My SONY Nightmare

I bought a SONY VAIO RX-770 on July 6, 2002. On the first day the machine froze up on the internet. That was my first of over 20 calls to the SONY technical support group. After 3 shipments back and forth to SONY's repair service center in San Diego, my PC finally is in operating condition. My PC spent approximately 5 weeks in San Diego and had a better vacation than I did. They replaced the Modem, Motherboard and finally the CPU. It is now almost 3 months since my purchase, my PC is finally operating correctly. My e-mail inquires to SONY received no response, my phone inquires to management received no return calls and the phone center personnel broke their arms patting themselves on the back for doing such a great job (?). It became chillingly apparent to me that SONY was not interested in customers.
