After having to work with Akamai as a vendor in several positions (it being out of my control to use a different vendor), their corporate attitude doesn't surprise me at all. Apologies for your experience.
+1 I've had to work with them a few times, Akamai has built up crazy infrastructure and I'm sure they have awesome tech behind it but getting them to actually help you as a customer if you're not a Fortune 500 company is useless. This is even when I was working at a company that was paying them in the 7 figure range per year.
Then my sympathies to you. But people who've been in this industry far longer than I have assured me - it's pretty damn normal.
Oh, and people in other industries have told me it's par for the course everywhere.
This is why networking is so important. That's my main advice to give. Meetups, user-groups, etc... get involved in them and do your best to learn, interact, and "level up" (to steal a brilliant recruitment/marketing slogan from the big A)
