This.

I once sat on a torrent for two months in order to get it completed and that was with broadband. Hell, I remember a torrent on MySpleen that had been dead for nearly 6 months before a seeding request was fulfilled, allowing me and another person to complete it.

Back in the 90's, before I had broadband, I dialed into my ISP for a weekend in order to download OpenBSD (1.5 GB). I stayed online the whole weekend (there was no way to do partial downloads back then). Even if you have a bandwidth cap, you should still be able to get it if you give it enough time. Download half your bandwidth cap each month and eventually you'll get the whole thing. I know 8.5 gig is a lot and the waiting will be a pain, but you'd get it eventually.
