At&T Prepaid phone card plus
We have used the same At&t prepaid minutes card for many years. We just add minutes when it gets low. In the past 2 days it no longer works even though we have 891 minutes left on it. When we call the 800 prepaid minutes customer service it says it is an invalid # but we know it is a good number. There is no way of getting a "live' person to hear and help with our complaint.
