Requesting refund for $100 tech visit fee

I'm an existing Xfinity customer and recently moved to a new apartment. I requested a service transfer and tried to self-install using my device from my old place. It didn't work, so I went through the Xfinity assistant to debug. We tried multiple attempts and none of them worked, eventually I was scheduled a technician to help.

Turns out my device was fiber-compatible but my new address doesn't support fiber -- so the tech swapped it out with a compatible one. However, now I'm seeing a $100 one-time charge on my bill. It was a bit unexpected because:

• Failure was due to a network compatibility issue at my new address, not user error.
• The virtual assistant didn't identify this issue. Had this been identified, I would rather just pick up a new one and install by myself instead of having technician to visit.
• I wasn't informed of the $100 visit fee and only got to learn about it after my billing came out.
• The visit was essentially an equipment swap, pretty straightforward.

Given above, may I ask for this to be refunded? Could anyone from the billing team please help take a look? Happy to share account details over DM.
