Annie - what I would do is first, find the ICQ contact info of someone from the program and send them this link to let them know that although their name was not mentioned, it's them you are referring to.
If it's happening to you - and to your friend - something's funky. Either it's a cookie issue, programming issue or there is no referral program.
If you know the backend software being used (if it's not a custom code), you should perhaps contact the company that made it to ask if there's possibly a way that it's a programming issue.
Personally, when sponsors don't reply to email - I find their people online via ICQ - if I can't find their ICQ, I find people that know them personally to get the message across.
Sometimes it 'could' be an email issue - but obviously, if they aren't getting the emails, they aren't getting the complaints about the issues either
