Lately my internet speed has been all over the place, I have done the online support and it didnt help. It worked fine when they "tested" it aka made me restart my modem.

and moments later at another nearby server.

I only have the one computer on and I am paying for 75Mb/s ( megabits). Then it spikes back to my normal speed.
During the time of the speed test, I was the only one online, the only other verizon service that was running was our TV.
Questions:
-What can I make verizon do to solve this issue?
Edit: these tests are on a wired connection.
And now its back to normal:


my biggest issue is it basically kicks me out of some games due to the spike.
