JPMorgan Chase Credit Card Complaint

JPMorgan Chase Credit card department,

Credit line increase/decrease Illinois

I have had different chase accounts for some time now without any issues and always paid my bills on time. Recently I received a notification via a third party app I use that my credit lines were decreased on both of my chase cards. I thought the notification was an error so I logged on and noticed that my limit was reduced just - or so dollars above my balance. This has caused my fico score to crash and my utilization to sky rocket hurting me for no apparent reason. I once again have been late or exceeded my limit but I was punished.
