Very unhappy customer

I am without internet since last Friday, one week ago. I have made numerous calls and sent messages for assistance to get my internet back up and running. The consultants contacted me to try and assist, no luck, I get cut off each time I phone them. Yesterday they told me a technician will be in touch to come out and assist. I have still heard nothing. This is pathetic service and really annoying. I cannot believe the bad attitude, they do not care about a person being without internet for a week. I need internet for my work??? I am so annoyed, wish I had never signed up with them. I cannot seem to get through to anyone that can give me positive results. What more must I do to get my internet up and running again???
