Callective Energy phone call regarding PG&E Bill?

I got a call from "Callective Energy" regarding a subsidy on my PG&E bill. The woman initially told me they'd give me a 35% discount and asked for my Service Agreement ID which I gave them and my "Rate Schedule". Both seemed innocent values so I provided them.

Then another guy hopped on the phone and he said I was exercising my California right to choose my energy provider which is where the yellow flags became red flags.

I didn't find any immediate info on this company although they are listed on this PG&E page.

Anyone know what's up?
