Upload; IPv6 issues

Hello, about 2 days ago a couple of devices, mainly my desktop and laptop have had issues with loading certain websites, and when I run a speed test while I have great Download speeds and low latency, my upload speed is either 0 or pops an error during the speed test. I have tried to talk my way through it with the Customer support chatbot and it either gets stuck at the modem restart step or it says it has plain trouble getting my internet packets to test the connection. I was expecting at this point to able to schedule a technician appointment, but that option isn't showing.

To workaround the website loading issue, I disabled my IPv6 on my Desktop's network adapter, but even though that fixes the website issue, I'm still seeing an issue with the upload speeds. It's making it so I can't even attach a small file to an email. 

Is there a way to get a tech appointment scheduled or walk through this issue with a non ai-chatbot? Thanks!
