Another gripe I have with some of these companies is about mail-in-rebates... I've given up on them.
Norton offers mail in rebates for buying their products when you are upgrading... well I was. They say "if you have a qualifying product". Well if I'm going from Antivirus 2004 to Antivirus 2005... wouldn't you say that's a qualifying product? I waited and waited and finally checked up on it and they said that I didn't qualify!! I said forget it, it's only $20 bucks. I'd rather let them keep it than spend hours of my time talking to someone in India for hours about it.
Another company that stinks with mail in rebates is Ultra... haven't seen a penny yet jerks!!! (I hope you're reading this.)
Also, have you had this happen? You go through the whole automated message thing where you have to press 1 for this and 3 for that... and you spend about 10 minutes before you talk to anyone, and then when you finally get through the reception is so bad that you can't hear or understand anything they're saying, but you can make out (in an Indian accent)... "I cannot hear you so well... your phone is bad!"

Well of course not! You're on the other side of the PLANET! Then you have to call back and do it all over again.
Let me not even get started with Tiger Direct. They're based out of Miami where I live and they have outlet stores. Their return policy is the worst I've ever seen. You can't win with them!
