bought premiere after signing up

[TrillSouth]

I bought the premiere bundle after signing up for the two months free. I just did that a few days ago and just got my bundle today. it included the 3-month code can I get my free extended to 3 months instead or add this 3 months to the two free?

@TrillSouth As I understand it, the 3-month trial bundled with the hardware kit is only available to first-time subscribers; you can't use the code to activate an existing account. 

There are a bunch of FAQs on the various combinations of trials and subscriptions here:

I know that's the problem because I only bought the premiere 2 days after activating the code
