Update: I emailed them explaining that I would need to cancel and deactivate since I did not plan to obtain an EIN. This was their reply:
You do not have to obtain an EIN number until May. You are still able to do assignments until then without an EIN.
So, I guess that means I will do the April pizza shop. I better get paid!
I have decided not to deactivate. Im gonna stay active so I can see how desperate they get. It shall get interesting.
