Hmmm... in my own opinion I think they won't do anything about it in the first place, they probably wanted to scare you with what they said - unlikely but just a thought (like they getting a lawyer etc.) because it's really ridiculous that they called you about a Dolby license lmao.
But in all seriousness that was messed up saying that you responded to them saying you got an invite link, which made them suspicious. (You could've lied saying it was from a company that you was working with, but they'll want details and proof :| )
When I received the call from Adobe, I was in panic. I knew I should have stayed calm but everything went so fast.
Any updates on this? Curious to know, first time hearing a company do that. Also don't be fooled from the number. You can easily spoof numbers. I use to prank my friends with spoofed numbers all the time.
