Who I have the same questioned this topic

Ok I need someone to clear this up for me please. I am a Verizon prepaid customer and I went to a Verizon Wireless store to buy a new Verizon prepaid cell phone because my old one is starting to fall apart. I was told at the store that if I wanted to get a new phone that I would have to get a new account and a new #. And that if I don't want to change my account or # then to go to a store like walmart or radio shack to buy a Verizon prepaid phonr and switch my account and # to the new phone my self. Has anyone heard of this? Is this really true? Thanks!
