These people never answer the phone or return calls good luck with getting in touch with them

Once again sons bus is over an hour late, no one answering phones at transportation (which is every time I call). How are parents expected to sit at a bus stop for an hour? This is literally 1-2 times a week. He is 6 and says school gets out and they are walked to watch a movie while they wait for a bus to come get them. Way to inform parents. Like I said, it’s October and this has happened at least 10-12 times.
