Internet Service Issues.. Packet loss and Latency

I recently started having issues after xfinity send me a text message saying they were going to do "work to enhance the network in your area". This happened on 3/18. When the "outage/maintenance" or w/e they were doing ended, my connection came back, but now I always have packet loss and Latency issues. Having phone calls/meeting while connected is impossible and playing any time of online game is also impossible.

When i try to call or chat with a REP it keeps saying there is an outage in my area and that they cannot connect me to rep. These has being happening since 3/18. When is this going to be fix ? how is it possible there is an outage going on for almost a month ? I though you guys were "enhancing the network" ? what is going on ? Can i get some help from an actual human please... 

I have tried everything on my end and I'm pretty sure this is issue is from outside.
