Month 4, still no stable internet

I had a previous complaint and my line got fixed for about a month. Now it has been 4 months and I still have no stable connection, in fact my internet is not working at all!!.<br> <br> You had a technician at my house and he only took the connection from unstable to unusable. You let me pay all that money for 4 months only to never deliver on any services??. <br> <br> You are costing me money, I work from home on certain days and without internet its worthless, just like your service!. There is a high probability that you will need to change the copper wires as that seems to be the issue so i'm just assuming that I will never have internet again!.
