Legacy Pay As You Go

This is what happened to me this morning:  I didn't let my gold account expire, it expired on it's own - 9 months early.   I added to the balance last October 2024 and the web receipt shows an expiration date of October 18, 2025.  3 months later I turn on my phone only to be greeted with a suspended account text and a zero balance.  (Balance the previous week was $114.)  CSR said it may have been a glitch but didn't know for sure and said the balance would be restored in 72 hours.   Have had this plan 17 years and this is a first.
