Fiber Optic Gigablast service unusable through VPN do to slow speeds

All was well until about July 2019. My upload speeds without VPN were 900, and my speeds through my VPN (Cisco AnyConnect) were 250 connecting to my hospital network.

After that, my connection without the VPN stayed the same. Through the VPN, however, speeds dropped to about 8. Unusable for my needs.

For a short period, speeds went to about 40 for about 2-3 weeks in Sept or Oct, then back to 8. Today I'm at 6.

One of my partners, and the IT director of the hospitals have fiber, and the same problem.

After extensive testing by the hospital IT team, they determined the problem is definitely on the Cox end. A level 2 or 3 Cox IT employee went to the home of the IT director, ran his own tests, and confirmed the problem is on Cox's end. That was weeks ago. No communication, known action, or resolution.

In the mean time, I'm still being charged over $100/month for a service that does not perform anywhere close to advertised, and is useless for my work needs.

I have spent 4-5 hours, made over 20 phone calls, and had 2 no show service calls attempting to get a second line (Coax with speeds "Up to 300", which is what I'm told by Cox is my only other option at this time to connect to work with usable speeds).

I get nothing but the run around. People say they will help, try to schedule an installation, and the system won't process the order. When I try to follow up with them, they don't answer, return my messages, or respond to my emails.

Any assistance or advice would be welcome. Thank you in advance.
