Extreme packet loss issue

I have been getting extreme packet loss starting in July, in the new apartment I moved into back in May. It is intermittent meaning outside of the moments when packet loss is occurring it is perfect.  I am using the xfinity modem with 800 mb/s download speed. 

I have been on the phone with 20~ customer support technicians, each of them basically telling me they have no idea what's going on. They have promised to escalate me to higher ups who can help, but they never call me back to help when they say they do. I have also had 3 technicians come out to help me, each of them checking wires and cables inside the apartment and outside. The first one told me he had no idea what was going on, he didn't even know what packet loss was. The second and third one said they removed a filter on connection point on my floor which they said should help, but did not. They called in xfinity techs to do service work on the lines outside in late August, which seemed to solve it for an entire month, up until 4-5 days ago when the packet loss issue returned. I have called customer support again and they told me they don't know and are sending a technician out again. 

Here is a picture of the pingplotter for reference. I really do not want to go back through the hoops of xfinity customer service again. I work from home and do online gaming and this makes any work I attempt to do basically impossible to accomplish. Does anyone have any suggestions for how to escalate this so I can actually get someone to help me? I consistently get hung up on by customer service reps and told they can't do anything. They refuse to escalate me to anyone that can actually fix my problems and it's driving me insane. The technicians that come out know basically nothing and do nothing to help. 

I cannot lose more time at work because of this issue. 

Please help.
