Google ads scam?

Was looking for some insight. I have a friend who I’m pretty sure fell prey to a tech support scam. Most of the signs point that way. Long story short, my friend isn’t that tech savvy and they were trying to get a printer set up. They ended up contacting a tech support supposedly for Canon and got into a remote desktop session. The “tech support” ended up getting into my friend’s Google account and created a Google Ad campaign under their username (Google Ads 682-219-7894…phone number, maybe?)(ad campaigns were for things related to public speak and such). I did some digging in the browser and account histories and stuff just didn’t add up. Oh yeah, and this whole process to “install” a simple driver took over an hour and a half.
We went in and changed account passwords and what not to be on the safe side.
Anyway, I’m slightly new to this whole thing and was wondering if anyone else has seen a scam like this before? Thanks for any info on this
