cm2000 Slow 1/2 speed of service

I was forced to upgrade my CM1000 to a CM2000 (from xfinity's approved modem list) and things have not been going well. I was getting 900Mb and now 600Mb on Comcasts speedtest The CM2000 status is good. I have attempted unsuccessfully to get Xfinity to address the issue as there automated and customer service systems say everything is okay. I am extremely frustrated as its it seems to be a provision problem

This is on top of all the outages
