Moving some features from RingCentral to Xfinity?

This forum is my last resort. I've tried to get some help from Comcast for 2 HOURS today and have been unable to! I've called several times, been hung up on by people who didn't speak English, and the last time was at 6 PM MDT when the guy who was supposedly helping me, gave me a recoding saying that they were now closed for the day, and hung up on me!

The web "chat" is useless! It wouldn't even  work after awhile.

I tried having the support number call me, and that didn't work right. 

I'm so disgusted, that I'm ready to give up on switching my RingCentral over here.

Is anyone reading this?
