New VM02 Nextfibre 2gb/2gb

Yes finally came back (sort of) but the problem still persists another example is when try and download a file say 5gb or 4k streaming - you can visibly see the download rate just stall after about 10 seconds of download and sits at 0b/s for a good 30 seconds before increasing to not even near connected speed sometime lucky it will hit 40mb/s download speed but the drops back to 0 and rinse repeat so in essence a 5gb file actually takes 1hr plus to download i mean on a 2gb connection? i know differance between mbits and mb/s for downloding but know this is very bad. As gameing it is near impossible in a team even (in my case warcraft raiding) to actually get anything done when half way through a boss fight the net just stops ms goes through the roof everything freezes for 5-30 seconds then catches up in as though game is running in fast forward to catch up that's if and a big if at this point it hasn't already disconnected me from the game.   This also i might add not only happens on wifi but also on a pc connected to a 2.5gb ethernet connection so whatever is going on the "dropping" in any shape or form is ridiculous.  I have now been trying to get another engineer out to fix whatever the heck is going on but cant even get past the screen that asks what the router is doing as the screen no longer comes up to show what the router is doing - so no chance of even booking a engineer.  Again earlier in this post "ring fences team" was mention - i still do not know what this is or how to contact them.  This is really getting unacceptable now as service is not fit for use - my old connection FTTC was only 25mbit due to distance to cabinet but never once experianced these issues in game or anything else just pretty slow downloads but understandable on 25mbit but never dropped or high ms etc or disconnects like i am getting on what is meant to be Ultrafast!
