consistent latency issues when trying to game

Intermittent latency spikes have disrupted my ability to game, so I have resorted to adding a Centurylink DSL line just for gaming. The line is slow from a download and upload perspective, but the latency is very consistent, which makes gaming possible. I would like to know if Cox would be willing to reimburse me the $50 a month that I have to pay Centurylink since Cox is unable to provide consitent latency. The issue typically occurs at my first hop which is I use pingplotter so I can see the latency and packet loss carrying through on the traceroute to just about any server I ping.
