Unable to get promised bill credit through phone support or link provided

Hello, we had an outage of our Xfinity internet service since the evening of July 3rd. After several repeated phone calls to support to attempt to schedule a service call and being unable to speak to a human to do so through the phone system due to an "outage in your area, we can't help you over the phone, goodbye" the system finally let me schedule an appointment on the morning of July 6th.

The first available service appointment? Today -- July 14th. A full 11 days after the service went out.

Thankfully the technician was able to fix the issue at the pole and restore my service during today's visit.

The original phone rep said to make sure to call back once service is restored, as I would be eligible for a bill credit for the days that I was unable to use the service. I work from home and was upset at the prospect of an additional expense for alternate Internet access. But this at least seemed a fair enough compromise.

So I call back today after service is restored, and the AI voice assistant texted me a link to an AI chatbot in order to request the credit. Which then took me to a webpage that won't let me enter a date range of more than 7 days.

It took 11 days just to get a technician to my house, yet the site lets me only choose a date range of 7 days? This makes no logical sense.

I pay over $100 a month for just Internet access. 11 days of this month I have not been able to access the service that I pay good money for.

Please help.
