The robot calls and emails stop when your kid graduates

We are weirdly having the opposite problem. My PK4er buys lunch almost all of the time (we only pack it if the lunch for the day is something she really dislikes. We have only gotten billed ~$22 since the year started, so like 7-8 lunches total, when average about 8/week. The teachers bring the food in for PK, so it's not like my kid is entering the number wrong somehow. Also, because it mirrors a question someone asked above, we're usually charged $2.80 but occasionally $3? No idea why.
