Poor Customer Service and Not honoring their agreement

On 9/10/2025 I called about my service  interruption. Agent couldn’t assist so I asked to speak with a supervisor. I got Sup Peter who was so rude - My issue was on August 20th 2025 I completed an payment arrangement to be scheduled for 9/18/2025 to avoid service interruption, but on 9/10/2025 my service was suspended. I explained that I have  the confirmation Text and email that arrangement was set up for 95.48 to come out my account on 9/18/2025 keep in mind all this shows up on their end too. Sup Peter stated that it had to be a system error and there is nothing he could do about it. I simply asked why can’t Xfinity be held accountable for not  honoring their part. Sup Peter told me that’s not his job and he don’t talk to customers and that he only speak with agents . Pretty much didn’t have no willingness to assist me even though he said it was an error . I am so disgusted about how I was treated.
