Terrible customer service

So yesterday my bill was 508$ and I was offered to pay 50$ to have my balance broken down into a 12 month installment plan and services would be restored. I didn’t have it until today. I was unemployed for 3 weeks. Now my bill is 800$ and my only option is to pay it all?? I’ve been with xfinity for 6 years!! Now I get a text messages that my services are terminated and I have to return equipment when I don’t even want to do that at all!! I’ve been expecting a “call back” from a supervisor for 2 hours now. My children need internet for school. I really don’t want to leave xfinity but it’s looking like it’s my only option.
