This is outrageous.

Deleting the whole account is really unjustifiable! If OP was abusing some service of Google, then ban him from this specific service, but why take his whole data?

If there is something to learn, it's to keep a local copy of anything you have, and never be 100% depending on an online service. But then this obliterates the benefits of investing entirely in so called cloud services with any company, including Google. Ownership of your data, doesn't seem to be one of those benefits.
