My Interne is very bad. Its going on for an year now. Level - 7 keep on adjust the rooter and signals. After a year with bad internet Level - 7 is telling me that it is my rooter that give me problems and they need to do a survey and to get a quote for an upgrade rooter. My case number *** is now hanging in the air for three weeks now and still waiting for the survey and quote for rooter. I keep on phoning Level - 7 and all what they can say is sorry, we are busy with your case.

The service is very bad and they going to keep on loosing customers because of the bad service.
