Payment arrangement problems

My whole family was hospitalized with covid we have 5 kids and our 2 yr old didn't make it he passed 4 days ago my bill is past due and will be shut off the 26th the day after xmas it says in the app im eligible to change my due date so it won't be shut off the problem is it's showing October and November dates instead of December bcuz of this i can't use the service to keep my account i called and spoke with agents who were aware of the problem but told me there's nothing they can do to change it i used online due date change over the automated system on the phone and i also tried the chat option on chat it won't let me change my user role I've had this account before covid-19 and always pray even though i made them aware that we have kids in school our child has just passed and the internal glitches that stopping me from setting this up they still won't help me and also told me that even tho the disconnect date is 12-26-20 it'll be shut off xmas day the agent who i spoke to promised to call me the next day to help resolve this so we can keep services but she never did I've tried calling back but since I've been so busy getting my dead chil dressed to bury him and trying to give the rest of the kids some normalcy not to mention it's noted on the account we've had numerous problems with our service and we still payed now with the worst time of our lives xfinity doesn't care about the customers even when it's the companies fault thanks for nothing I hope you've enjoyed the 200 we've been paying every month
