Luke from Fidelity.com called me from this number.

Jeff, my Fidelity.com guy, called me from this number.

904-486-5300 (Florida) Micheal Mackey from Fidelity called my cell #.  Said he wanted to talk about my investments.  Told him I'd call him back when it was convenient for me and he gave me 1-800-642-6975 x 4624 as his call back #.  Just googled that and it did not match anything.
