Service disconnected with payment extension plan

I contacted Xfinity via Chat 10-19-22 re: timing to resolve my past due balance and avoid losing my service.

The agent approved a payment extension until 10-27-22 for the past due balance.

They assured me my services would not be disconnected as long as I paid the past due balance on or before 10-27-22.

The next day 10-28-22 internet & cable TV suddenly disconnected.

I called Xfinity but the system would not allow me to talk to anyone or schedule a call back  "an agent won't be able to help you until we receive your payment"

I finally got connected to an agent via Chat and explained the situation.

They said my services were suspended because I was not eligible for the payment extension approved by Xfinity agent 24 hours earlier.

The only option for restoring my service was to pay the entire past due balance immediately.

I explained several times that the past due amount is too much for me to cover now before I get paid.

I have screenshots of the original chat session indicating the payment plan was approved.

Please help, I need internet service for work
