Anyone know how to cancel the IDEA Membership? They don’t answer the phone or respond to emails and the “Live Chat” is offline

“Cancel”? Do you mean you are asking for a refund? (I’m pretty sure that is not an option–I’ve never heard of it being an option with professional organizations, associations, or societies, actually.) When you get your renewal notice, simply ignore it, don’t pay the dues, and your membership will end.
