Xfinity Internet Essentials problem

Three months ago I called Xfinity Internet Essentials customer service. I asked to reduce the payment for my Internet because I am disabled and have not worked since January 2024. I was told to wait 2 months for my payment plan to be changed. 3 months have already passed but I receive a receipt for payment for $ 43. I have already accumulated a debt of two months $ 98. Can you help me with this issue and what documents do you need to send me. On the Xfinity Internet Essentials website, I tried to apply for a discount on the Internet, but at the end of filling out the application it shows me that there is already Internet at my address and does not allow me to fill out further for benefits.
