Internet basically unusable after my neighborhood upgraded to 10g

So recently I got the notification that my neighborhood was upgraded to the 10g network. Since then my service has been getting worse and worse. I have noticed over the weeks more and more that websites, streams, and videos are taking longer to load as well as getting connecting errors and getting disconnected from games are happening at a greater pace. As a few days ago none of my devices can get signal from the wireless and my computer can barely load anything much less play an online game.

I ran several tests with the xfinity app and I am currently getting at most 14-21% of the 1gig I should be and my latency has sky rocketed. I also am not getting my phone (voip) service at all as it says no line on the phone its self and wont even getting a dial tone. I even bought a brand new basic phone to swap the old one out with, but it still says no line. 

I did go to the xfinity store today and swapped out my modem as it was several years old and figured to give that a shot incase it had gone bad. After getting home and setting it up nothing has improved. I did get a tech scheduled to come take a look, but it will be days before they can come out and was hoping to see if anyone could help me in the meantime.
