Intermittent Internet connectivity loss

My Internet is constantly dropping, and my

ping has tons of big spikes. I have had about four techs come out to my apartment to try to fix it. One of them submitted a ticket and said someone else had to come out. It did not resolve the issue so I had to have someone else come out and said that there was already a ticket in and nothing has been done I would like a supervisor or somebody to come out. I can fix this issue because it’s been going on for a long time. The techs have identified issues with the signal when they come here, but it is not been fixed.
