Promotion expired: affordable Internet renewal and October bill review — written support needed

Hello, I need an Official Xfinity Employee to help review an affordable Internet-only renewal and my October bill.

My promotional discount expired and my monthly bill increased by $60. I am a current graduate student on 1 Gig Internet with an included Xfinity Gateway. I want to keep my existing account and Gateway. I have only 1-3 devices and am comfortable with 300-500 Mbps if the total monthly cost is about $40-$60 including taxes and fees. The $70 and higher offers from online plan management and live chat are outside my budget. Could you check existing-customer, loyalty, retention, or student renewal options? I do not need a mobile bundle.

I also requested review of my October bill. A live-chat representative said a backend adjustment would be reviewed within 7 days and a reference number would be emailed, but no amount or actual reference number has been provided. Another representative has not verified that request. Please help confirm whether a request exists and whether a courtesy credit or prorated adjustment is available.

I need written support because I cannot reach the phone team or receive their callback. Please advise how to continue securely with an Official Employee here. I can provide account verification privately when requested.

Please provide quotes and review only. No plan change, order, cancellation, payment, or phone callback is authorized. Thank you.
