Internet Speed

[Keruby]

I have been a customer for more than 10yrs now. And i am one heavy online gamer and everytime you guys mess up with my speed i notice right away!!! Why is it that from time to time you guys keep lowering my speed??? I have to be calling for a tech to
" troubleshoot" and fix the problem. This is not right and shouldnt be happening. Right now it went down to 25.5 mbps. When iam always at 400 and im getting sick and tired of having to call someone to fix this. Why? Just why????

Thanks. I will save it for future references. I fixed it yesterday right away using the reset thing on the app chat. But it kept going from 411 down to 35 then 80, 111 and 95 then up to 300 and that was the last time i checked. Idk about today i havent checked. It's just annoying. Why does it happen?
