Imagine if 10% of service worked this way

Sent the following e-mail to Afrihost support at 10:44am on Sunday 21/07.

I notice this morning I have an email from you warning I am close to my cap.
Checking the stats I see 19gb downloaded from my own phone number in the last 24 hrs. (21/07)
This is not possible.
I have been home and the sole user for this entire period.
Can you provide more details please?

Received the following reply 3 hrs later:
