Can I have your customer number?
"Not a customer? Sorry, we don't want to hear about our product unless you've actually given us cash in the past".
Typical response trying to notify peeps, been there, done that. But then again, there is a "reason" why it's so hard to reach the right person.
That guy/gal is probably wearing 15 hats and hiding from their paying customers. Don't have time for free lance help desk tickets...
