New Orleans-area Cox Cable service is terrible

We've had macroblocking for the past six months and tonight every channel is cutting in and out. If this keeps up we won't even be able to watch MNF. When we called to report problems last month, they said it was due to water being in the line and the problem was cleared up. Funny thing is, everyone I talk to in the metro area has said the same thing. We get nothing but interrupted service and they'll probably end up raising their prices yet again.
