No Service

After my relocation which happened 3 weeks ago I was supposed to get a new password and user name which never happened. Up until today I've been calling Tech support and sales. They keep sending me back and forth saying they cant assist I call Tech support to assist and they say sales must assist me then I call sales and they say tech support must assist me now who the **** is going to assist me. They say I need a TIN number which I never got. I also need my new username and password for my router which I never got I'm getting ****ed off of calling and nothing happens
