$100 Charge

Hi!

I recently took my working cable box from the bedroom to the guest room. Unfortunately, the cable box does not work there (it was working perfectly in the bedroom). After spending a few hours with agents trying to get it to work, it was determined that there is likely faulty equipment in the wall outlet and that a tech agent would need to come out to fix it. I scheduled an appointment and have someone coming out later this week. In the e-mail confirming the appointment, I see that there is a $100 charge for a "pro install." I called to discuss this with an agent who says that this is a "relocation" fee due to me taking the box from one room to another room. I don't need help with installing the box. My understanding was that if the issue was related to faulty Xfinity equipment that there would be no charge (as I've had someone out as recently as the past 4-5 months at my previous location with a similar issues). Can you please let me know if I'm incorrect? If I'm correct, can you please fix the bill and take the $100 fee off? Thanks!
