How can an issue be escalated within Cox? My plan was messed up, my paid for services were discontinued and in order to put the services back, I am required to pay almost $40 more. My bill did not decrease, I lost my channels/packs I am paying for and no one can fix this issue.  I did not make the change and I have to pay for the mistake each of the 13 agents I spoke to can clearly see. But no one can fix this
