Endless Latency Issues with no help.

Hello,

I'm hoping this will be the way in which someone finally helps with an ongoing issue. For the last month, we've been experincing phases of extreme latency, resulting in slow internet and even in some cases, interent dropping. I've checked everything on our network end, nothing indicates as a problem. I've been running PingPlotter for over a week now, with a laptop directly plugged into our modem and it still shows us having groups of latency. 

PingPlotter is indicating the signal is fine coming from our computers, to the modem, but it's slowing down several hops away. We end up with latency as high as 900 in some cases, along with packet loss. 

I've had 5 techs sent out to find out what's wrong, each of them plug into our modem and say it's fine. Each of them insist that it's our network, despite me attemping to show them the Ping results I've been gathering. No one wants to see them and no one seems to care. I just get people trying to sell me bandwitdh (which I don't need), despite my findings that we are extperincing latency in times our business is closed and no one is even using the internet, except for my lone pinging laptop. 

I've contacted as many people as I could, talked to several customer service reps, I get Reference number after Reference number, but no one is doing anything about it. 

I would just like someone to look at the Pings I have, see the evidence that it's not our equipment and at least, attempt to find out what's causing the the issue. 

Thank you.
