Keep calling and opening up tickets. Also, ask to speak to a manager or one level above that even. I had 25+ trouble tickets the first 2 years I had DSL from Sprint (Centurylink). Since I work in the the networking field I know how to trouble shoot and isolate the problem. I would tell them where the problem was and then have to spend an hour on the phone while they did their tests. I finally got got the point that as soon as I opened a ticket I would as to speak to a manager. Doing this did help. Another thing to do is if you have a gateway instead of a modem log into it and look at the line stats (db levels, ATM errors, etc). I would post those numbers on dslreports and see what the folks on thier say. I know that one the Sprint/Embarq/Centurylink forum there ar several employees that provide input to try and help people out. Good luck, I know it is a pain on the ass.
