Who I have the same questioned this topic

I'm constantly on wifi working in an office and doing online graduate school after work so it just doesn't make sense and the online chat has been extremely unhelpful. This is almost a monthly to bi-monthly issue for me. Online chat and customer service only asks questions about wifi assist and background refresh (all of which I have off) and they give me where my data is going but no one can explain why I'm running out when I'm on wifi.
