Worst service I have recieved this year

Average waiting time to Speak to a support agent 50 Min, Then they promise to contact you and never do. Wait 50 minutes on hold again, explain the problem get put on hold, then line Dropped. Send a request for a call back every 90 minutes for 6 Hours give up. Call the next day 40 Minutes on hold then speak to a agent who will get manager to contact me. Nothing Happens. Drive to their office speak to Domenico he promises the world but nothing happens except he gives me a Fiber Modem with no Line installed. Wait 5 days Finally get to speak to manager (65 Minutes on hold) he promises to get back to me 5 days later I am righting this post.
