Home phone not working (Xfinity Voice) and my upload speed is .11 (supposed to get 35mbps upload speed)

I got a new modem from Xfinity and the home phone is plugged in but doesn't work (I didn't see an error code so I assumed it was working). If you call it, it goes to voicemail, no ringing. Chat on my computer won't troubleshoot it... only restarts the modem and confirms internet is working. No other choices to get support. Is there REALLY no support?

I have a 4 year old Dell desktop w/3TB of space 32 GB memory and my upload speed is .11 mpbs and download speed is 785 mpbs and I'm paying for download speed of 1,300 mbps and upload speed of 35 mbps. I pay $360/mo. which includes Super Triple Play and Xfi Complete. Can't get any support and I've scoured the web for why this would be and the Xfinity app tells me that I'm getting 1000% of my speed (but the app also told me that I don't have voice services and directed me to purchase it, so there's that...).

This is insane. Absolutely insane. Fios is in my neighborhood. I'm not sure why I'm even bothering trying to get someone in person. I went to the store regarding the speed and they gave me a new modem (after 7 years with my old one) and I figured that would help. I went back when it didn't and they didn't want to take the modem back or help me. They were like 'nope... next person.'

I noticed the speed [Edited: "Language"] back in March and a salesperson online talked me into xFi Complete $25/mo. and told me a new modem was coming. No modem came and I quite frankly forgot. Now I'm having issues and they gave me a new modem but I had to go into the store and like I said, they don't want any part of helping... only interested in selling me more services.

I have very little faith that even posting here will help. But FYI Xfinity--your support [Edited: "Language"] big time. If you have internet that works, they feel they've done their job, the app lies about speed and there is not support for home phone not working.
