I will point out Vanguard has never tried to upsell me and Fidelity has. But when I told Fidelity never to call me again, they have complied.
I met with a Fido rep once to have some Vanguard accounts moved to Fidelity. The guy kept pushing what he called an index fund, but he wouldn't give me the ticker. I wasted an hour with him then several emails before I realized he was trying to push me into an AUM account. I sent a very angry email to the branch manager.
