Service interruption when assured I was fine

I am behind on my bill. I talked to two agents the other day, one saying that they will extend my automatic payment date until when I needed it and between those two dates, I would not see an interruption of service. I have a screenshot showing this. 
They ended up not putting the extension date on my account so I had to talk to a second agent the same day. This one made the date of my automatic payment incorrect, said they picked the right date, and told me it would update later in the app. I also have a screenshot of this.
It hasn’t updated last I checked and I still had a service shut of date of the 11th. 

It’s now the morning of the 11th and my service is suspended. I can’t talk to a live agent without paying my past due balance to get this corrected. This is frustrating when I was told two times basically that I would keep my service until my new extension date. Once I’m caught up on my payments, I am seriously considering choosing another provider after ten years of being a customer.
