I;m a bit confused, igo mate:

"Actually my issue is that I had reset my Hex upgrade twice to get the upgrade but both time I could not get to a broadband connection to even download before the time ran out"

This isn't DAZ's fault though, surely - that you reset your downloads when you had no way of downloading?

"But to deny me the upgrade to a paid for piece of software (and in consideration of ALL my other past purchases) well, that I will pursue, after all I 'paid' for it."

But... you've said yourself that DAZ haven't denied you the upgrade. You've requested it twice, they've made it available twice, and you've let the download lperiod lapse twice. that's not them deniying it to you, that's you refusing to take it. Why NOT reset the download when you're actually at a computer that could download the product?

As for blaming them for not resetting the product further - I don't think you can blame them for something you suspect they MAY do (refuse to keep resetting the download) and blast them as if they actually had done it. Sure, DAZ lacks morals in the worst way, but it's pretty rich taking them to task for something you suspect they might do in the future based on your current rather stressed-out seeming behaviour. Isn't it?
