Hackers deleting invoice from webhosting company

Indicating the high levels of cybercrime, hackers deleting invoice emails from webhosting company
Since the domain investor has a large number of webhosting a/c, she is usually relying on the invoices to make payment
yet in one case the invoice was not received.
Only when the webhosting was suspended, the domain investor checked and found that one invoice was unpaid
The domain investor alone is spending her time, yet showing how ruthless the hackers making far more money are, they are deleting the invoices to cause further losses.
