Intermittent packet loss and high latency

This started a few weeks ago. Around the time Cox started construction in my area. One evening lost internet completely, reset modem, and since that night, keep losing connection. I work from home, using terminal services, and constant packet loss, even 3-4 packets causes disconnects. This is critical to get resolved for me. I spoke with a tech and they claim its my router and modem, and tried to up sell me on higher tier service! Unbelievable! No way to prove the issue is on their end, what am I left to do? They will not send out a tech unless I pay. I am not asking to check anything inside my house, check the signal outside at least. I have a Motorola MB7420, known to be one of the most reliable and a Ubiquiti PoE router, again, not the typical cheap Netgear or Linksys, but an enterprise quality router, known for their high quality. What is my next step here? Will this ever get fixed? I am not looking to get credit on my bill, just need this resolved ASAP! 

Some ping results and modem connection status and logs.

    Just to add:

    1. No splitters

    2. Verified all connections

    3. Rebooted router and modem

    4. Rebooting modem helps for about an hour then back to dropping connection

    5. No WiFi, directly connected via cat6 cable, and tested cable to confirm no issues
