URGENT BILLING/HARDSHIP HELP NEEDED — CONFUSING PAYMENT ARRANGEMENT DATES

URGENT BILLING/HARDSHIP HELP NEEDED — CONFUSING PAYMENT ARRANGEMENT DATES
I am NOT asking Xfinity to forgive what we owe. We fully intend to pay.
An agent previously gave me a payment arrangement for the 18th. That arrangement was specifically for the past-due balance of $108.98, which was something we could manage once the money became available.
Unfortunately, I was disconnected from the conversation, and because I was worried about losing our internet, I ended up setting up another arrangement.
Now the account is showing different dates and amounts, including the 11th and the 13th, and I honestly do not know which date Xfinity is going to use or when our service could actually be disconnected. There also appears to be an additional late fee now, which makes the situation even more frustrating because I had already been given an arrangement for the $108.98 past-due balance on the 18th.
My wife and I are trying very hard to keep everything paid while dealing with serious medical and financial issues. We are simply asking Xfinity to please honor or recreate the arrangement I was originally given for the $108.98 past-due amount on the 18th, or provide a short hardship extension that gets us to that date.
I spent roughly two hours trying to resolve this through chat already and was disconnected without getting a clear answer.
Could an official Xfinity employee please review the account, explain which payment or shutoff date is actually correct, and see whether the original arrangement for the 18th can be honored?
I will gladly provide my name, service address, account information, screenshots, or anything else needed through private message.
Thank you for taking the time to read this. We are not trying to avoid the bill. We are just trying to get through a very difficult stretch and keep things stable for our family.
