Good. I see four tests, two of each, starting at 8:41PM. You are using the right sizes, too. That's good. And, although we are in a peak usage time period, those speeds definitely look quite low. If you are able, it's best to run the tests at various times of the day to see if there are any differences. Also, again if you can, when you do a batch of tests, it's best to run at least three, and space them at least five minutes apart. Then, as stated, try to do a batch at different times of the day, if you are able.
Also, in case you didn't see above (there are a lot of posts so sometimes things can be missed), it is best to be directly connected to the modem, without the router being used, especially when trying to diagnose a low speed problem. Sometimes routers can cause problems, so it's best to eliminate them when doing speed test.
If you can, try to get a few more tests in, maybe a little later and some tomorrow. You obviously can't do them while working, and nobody would expect you to. Plus, you have to go to bed sometime. LOL. Just try to do a few here and there. That will give a good idea of your average speeds and the higher and lower speeds can help in determining what's causing it.
Hopefully they will be able to determine what's going on quickly and have you where you should be.
