I agree. I'm a huge fan of Google. I honestly don't even expect them to support their 'free' products like Gmail with 1 on 1 customer service. I frankly wouldn't either.
But when Google has your actual cash as in the case of Google checkout, and you can't even get a decent reply from them? That really shakes my faith in them as a company.
Paypal
Why does everyone assume paypal has no support? There's a contact link right on their homepage with email and phone support options. If Google wants to be in this game, I believe they should have to offer the same, especially in cases like for Android developers who have to wait a month to get paid.
Don't know why you got downvoted, when I had problems with my PayPal merchant account, I called a phone number and was able to speak to a real human being.
