My minutes on my AT&T go-phone service expired yesterday. I called today and added minutes, but I lost the balance that was in my account as of yesterday (approximately $50.00). I didn't not get any kind of notice that my minutes had expired. I had made a note on my calendar to add minutes today. I tried to get them to put the money back in my account but they refused to. This happened about a year ago and they did put the money back in, but today they said that was a one-time thing and they wouldn't do it again.
