Rude service and untruths

I was given misinformation about a payment arrangement through your billing department. I called in to Xfinity billing department on September 14th 2026 to set up a payment arrangement for me to pay my bill on the 29th of September 2026. The agent had me confirm through my email that the payment for the 29th was confirmed. However, My service was turned off today September 16th 2026, two days later. I called xfinity's billing department to see why this issue was occurring and was hung up on twice and yelled at by your manager who was supposed to be helpful. He was not helpful at all, but very rude and short-tempered. I tried to explain that I homeschool my daughter and I take online courses, and due to this issue of misinformation on your staff's part, my child and I both miss school today. I also let the agent know I'm on a fixed income and that's why I was making the payment arrangement in the first place. I really don't appreciate being disrespected and hung up on when it's hard enough to get someone on the phone in the first place. I was never notified that the payment arrangement was broken until my service was disconnected. If given the correct information the first time I called on the 14th of September 2026, I would have been able to pay the extra $75 that they're saying is the reason why my service is off but instead I was given a payment arrangement now I am hearing has has been broken by the computer system and would that have been said in the first place I would not be having this issue right now. Now every time I have an issue I'm going to have to file a complaint!
