I would cancel the order and take one of these paths

You'll need the license on the COA sticker to reinstall. The ISO is pure Windows, it won't have any of the Acer bloatware
Microsoft Windows and Office ISO Download Tool
Select version (Windows 7), Edition (Premium??), Language (Eng??)
Download the ISO
Burn to Disc or create USB
I would wait for Tuesday instead of paying money for old recovery when you can get it for free, spending time installing Windows 7, then deciding later to try win10 again.
You can download these things on a friends computer or at a public library. FedEx office rents computer time, but you need a few hours
