Speaking of contacting high level management I once guessed the email address of a UPS board member responsible for international business because of consistently awful delivery service in Sweden and customer support. To my surprise I was contacted after a few weeks by a mid level manager in Sweden and was eventually compensated.
This was about two years ago and unfortunately their excuse for service is ostensibly unchanged, rated as 1.33/5 on one of the larger national rating sites (at the time it was 1.4).
This seems like an immensely useful service (looking up executive level social media accounts). Are there companies out there who provide this service?
I work at a big company and get sales, marketing, press, and customer inquiries ALL THE TIME, at my PERSONAL email address (which is easier to find than my work address). There is absolutely nothing I can do to help you if you contact me directly because company policy forbids it, official channels exist for a reason.
Make a nice polite blog post with all of your documentation (including your sales receipt) and then send the link to him.
