I would setup an auto speed test to run over say a 24 hour period so you can first start to pinpoint the exact times after that schedule a tech to come out once you have a good idea of when it's going to happen and once it does he'll scratch his head and escalate the issue hopefully if not keep calling keep complaining unfortunately making as much noise as you can to draw attention to the issue is the only way to fix things and remember be nice to the technicians and customer support agents they do all they can but typically it'll take someone higher up like engineering to fix the actual issue depending on what it is
