Domestic abuser: "I tallied only 748 minutes of calls across these 9 pages, and after subtracting the 500 included minutes in your plan, we were only charged an additional $12.28 instead of the expected $12.40. Explain yourself!"
The most problematic ones, where this is most important, will definitely do so. A seriously unhinged domestic abuser is almost identical to an extremely scary stalker in demeanor, except they also live in your house and have access to an incredible amount of information about you.
Or... The abuser searches "why is my phone bill higher than my total minutes <carrier>" and the results are "Here are the 1 things that count against on your minutes, but don't show up on your bill: domestic violence calls"
Or they call the carrier and ask why the numbers don't add up. The carrier can't say "idk but still pay us". It's more complex than just saying that nobody ekll notice a few cents
