I was strung along by a telco; told several times that the issue was fixed only to discover on the next bill it wasn't. On my third (and what ended up being my last call to them), I told them I had the FTC's online complaint form open on my computer and was in the process of filling it out. I was immediately transfered to someone who said they will fix my problem and call me back in 10 minutes when it was done. They called back in 15 minutes, and I never had a problem after that.
