which free service (or service that pays you money, ala AdSense) has a better approach to customer service? Honestly curious because I hear a lot of complaints about Google, but I have a feeling that Facebook, Bing/Microsoft, etc aren't any better.
Google will assign a real person to talk to if you have more than ~30M views / month or something.
Paypal requires lots of paperwork here in the EU, sometimes their staff will make mistakes or ask you to provide information twice.
Facebook is horrible. In one case, when asked about something simple as their billing address, they gave the wrong answer (causing reporting problems). Their developer support is generally a real pain.
The difference is that if your account gets flagged for anything via any of their services they can lock you out of all their other services. This is the dark side of integration.
I know, I know, horror stories and everything. And the service or the customer service is not always free but at least you can speak to someone, you can have the process explained, you can appeal etc.
