I’m sorry that your friend did not receive the mail you sent him, but we can’t control your email providers. We’re good, but not that good. 
I suggest you look in your “sent” folder, retrieve the mail, and send it again. Consider an alternative mail provider if you have difficulties. If you were the buyer of that account, you can contact Support to ask that they send you the transmittal email again (but you must provide ownership verification, of course).
You mention a “contact us” form. If you mean the “Ask a question” form, we do send a verification of receipt. If you did not get that, I’m concerned again about your email account because you should have gotten a reply or replies. Why not start fresh: Go to this page, start up a ticket through the “Ask a Question” tab on that linked page, fill out as much info as possible and click submit. Providing they get the info, they will be able to assist you.
For tips on what information to provide in a ticket, please read this post and provide as much as possible to expedite the ticket.
