I give a negative -1 star if the rating allows it. This is because Zum school bus does not take any responsibilities or ownership in making changes to school bus schedule so that kids are pickup and arrived on time for school. Even after we have made multiple calls to voice our concerns to Zum. The scripted answer has always been, "We will look into it" but we never heard back from Zum. Meanwhile, we continued to observe that the Zum school bus has always been running behind scheduled pickup time ranging from 10 - 15 minutes. As a result, kids on the school bus are late for school daily. Zum knows the bus arrives late for school daily, but doesn't care to do anything about it.
