Google really need to sort their support out. When evaluating Google Apps for our organisation, we couldn't even get through to a human. This pretty much killed the evaluation up front.
I had a friendly human call me shortly after I signed up for a trial for work, and had good impressions of the onboarding process. But they didnt give contact numbers before that initial contact...
The problem here is that it's not just a Chrome Developer account, it's a Google account. There may well be an automated process to lockout users that owe them money.
Steam has a similar flaw. If you file a chargeback on any game you purchase then you'll be locked out of every game you ever 'bought' until you resolve the issue.
Because it gives me the best odds. Store-bought: can lose or break the disc, sometimes the DRM won't let it install on my system. Pirate: might be missing some of the data, might be invalidated by an update, always that slight fear of viruses.
Chargeback!
