Maybe you could tell us what the response was so we are not left in the dark. Wouldn't the response be important to the story? If the friends email works, it would solve the communication issue. Right? Like,

1. Do you actually have doors?
2. Do you have a record of my payment?
3. Did you get my calls and emails?
4. Did you ship them? When?
4. Call me by today or I want to cancel.

If the friends email works, get your info that way. Your "email to them" stream is screwed up. Don't fight that. Roll with it.
I don't get this story, starting to sound fishy from you now. They ARE responding but you don't say what they said, very odd? You don't need their personal cell number. Email your friend the message, he forwards it and sends you the response.
