Google has the worst customer support I have ever seen.
I once had to transfer a domain for a client that Google had registered with Godaddy. Google blamed Godaddy and Godaddy blamed Google. What a nightmare.
Same experience, I spent probably over an hour trying to get a domain off Google where Google went through GoDaddy. Wasn't able to make it work, gave up. Tried again a year or two later and did it after maybe 45 minutes.
