Curse a lot and rant, it works for me and they reply pretty darned quickly too. (Although they're generally a whole lot less than pleasant...they really need to work on their people skills a bit! )
LOL THAT must be my problem! I was polite and they only respond to scathing flames!
Oh well. I sold the 5800, bought a 9800Pro, so I've done the most I can to them:
1. Bought their competitor's product.
2. Told my story more than a few times in public forums.
Do they care? No. Will losing me as a customer matter to them? No.
Another of life's little exercises in futility.
