Error 691

So the technician comes by my house today, sits down at my computer, and begins to go on in chinese about how this isn't my problem. I reply that I know that, and that there was no point for him to come. Now there is a series of "Buck Passing" as to try and figure out why I can't connect to the internet. Long story short, I have been given a temporary username and password to try and connect with. I have serious doubts that this will work as my network icon seems lazier than usual, but i will give it a try in a few hours and see if it works. if it does that would point to a problem with my account. they don't seem to imply that i haven't paid, but this really feels like an account shut off, and no one else in the building is having a problem. I may end up switching internet companies soon, i get 691 with these people a lot but when the service is up it's really fast.
