Speak up if you are calling someone

I received two times called from same lady about their online store. Sad to say no idea what's her name and her online store name. Anyway it is about the online store's promotion, bad timing to call me I am not free. So I ask her what about, she says its about promotion on store.

Since it's online store, I think why not deal it the online way, so easy just email me the info.

So that's what I say to her, email me. That's it, end conversation.

Would you entertain someone who sound not confident and don't speak.
