Made technician appointment through the app, do I have to pay?

WiFi router broke, made an appointment to have a technician come to my house for a 1 hour service call and I didn’t see anything that said I would have to pay but I want to check. Do I have to pay for this technician visit?

Also if any of you have any advice how to fix my issue here is what’s wrong with it.

My WiFi router broke. Been at the thing for hours, my modem is perfectly fine but when I connect my router it lights red. I just did the exchange thing today to get a new router but it does the same thing on this one. Went through the whole chat to fix the problem thing on the app and they said that it was a device problem with the router so I needed a new one but the new one is doing same thing. I swear all cables are plugged in correctly and in working order.

It broke today when I reset my router and modem at the same time. Before it was working fine, just reset it cuz an issue I now realize was on my computer
