Slow WiFi Speeds and HORRIBLE Customer Service

I recently got Gigabit wifi and do not see anywhere near those speeds. My download speed in practice when installing apps or games is usually around 15 megabytes per second and peaks at 40 ish. I am running a wired connection from my desktop. I have tried multiple ethernet cords with rated speeds at or exceeding 10 Gbps but the 20 to 40 Mbps does not budge. I have changed which port I used on the router, and I have updated LAN drivers on the mobo. The mobo has a 1Gbps LAN port. Nothing has helped. I have done online speed tests. The standard google chrome one shows 18.6 Mbps. The google fiber website speed tests shows 98.8 Mbps. Using the Xfinity speed test website I get 432.2 Mbps but this seems really low for the 1100 Gbps advertised that I pay for considering I have a wired connection and it is even far below that number (by a factor of 10 minimum) when I go to use it.

The most frustrating part though is the horrible automated customer service. It asks irrelevant questions or does not have responses available for the actual problem I am having. Not having a person to answer questions is ridiculous. The bot just says that it works and hangs up after a while while it clearly is not working. Xfinity needs to have some real customer support.
