Hello, I am on a quest to have the Bot Parts Pack activated for me as well. I made a post about it here: https://answers.ea.com/t5/Spore/Please-activate-Bot-Parts-Pack-to-my-Spore-com-account/m-p/11956069#M14228
I have spoken to 2 EA Support Advisors about it and even tweeted about it! They all said the same statement that it's not possible. I have faith that it IS possible and I hold this post and all it's replies as the testimonial to the fact that it is. and these representatives simply don't know what I am even talking about. I am in Germany so it is harder for me in terms of calling them directly.
I have spoken as I said to two EA Support Advisors and Tweeted, though it won't let me even request a call or open another Live Chat anymore, maybe it is because I have two emails (accidentally XD) about it that I have gotten a reply on simply asking me what my Origin ID and email is etc (which I have replied to).
What to do you, or anyone else here recommend I do? I will give updates here. I have Direct Messaged EA Support on the matter also and detailed everything I know and even showed the users as for an example who have had this service granted to them. Wish me luck and thank you all.
