We were contacted recently by someone claiming this account and they were able to provide identity information.
If you are the original account holder of this account, I'd recommend contacting Billing immediately, as well as making sure all your systems and email are secure. I'd also be prepared to provide ID. When an account comes under contention, that is often necessary.
