AI Support Needs Improvement

I recently upgraded my modem.  I called COX to see what to do with my old modem.  After being connected to an AI agent, I requested a "real person" and was transferred to a "live agent" that I'm pretty sure was another AI agent.  I was instructed to return my old modem by a certain date (8/9) or I would be charged for the unit.  I was given three addresses that were supposed to be COX stores here in town, but they were obviously two casinos and the city's town hall (live in the Vegas area).  I searched Google for the closest COX store.  After leaving work and driving through traffic, losing 1.5 hours of my evening, the store staff told me that I owned the modem and did not need to return it.  Thank you so much COX for your crappy support and wasting a good portion of my gas and evening in traffic.  Rest assured when a fiber line from another vendor becomes available in my area, I will be jumping ship.  Oh and thanks for all the outages :)
