Unsolicited Service Charge

I was failed to be informed of a service charge, nonetheless a high service charge of $100. After accidentally unplugging the newly bought modem, the internet stopped working. The wifi would be connected, but the internet would NOT be connected. After self-attempting to fix the problem (restarting, unplugging and waiting, etc.), nothing was working. This led me to call customer service in which they attempted every fix via phone call, and still nothing worked. This further led to the customer service provider to create an appointment for a technician to step in. The technician tried everything I did—restarting the modem, unplugging and waiting a few minutes, etc.—and it was not working for him either. Afterwards, he ended up taking the old modem into his work van and replacing it with a brand new one. Now, Xfinity basically charged me $100 for replacing a new modem. The technician failed to voice that he was going to replace the modem. If he HAD VOICED THIS, I would have decline that service and do it myself. I’d rather pay to buy a new modem than this $100 fee. Xfinity rules says that there is no fee for replacing a faulty modem—which is what I had. I now have a $100 charge for replacing a modem from a technician when I could have done it myself if given noticed.
