I don't see the problem.
you asked when the drivers were comming out and he gave you a link so that you could see exactly when they were comming out.
you asked ifg they could be delayed, how the hell is he supposed to know, he's 1st line support not 3rd party development.
and he answered your question to the best of his ability, he's quite sure that the company qon't delay.
I don't see the problem at all.
