It's Cox wanting to sell you you either a phone plan or internet or more cable crap. I told them I wasn't interested and to please be taken off their call list and they haven't called back for weeks now.
These jerks call at least one a day, sometimes more. Most of the time they leave no message but every once in a while some retard will leave a message just saying "Hello" I finally called the number back and it was from Cox. I left a message complaining for them to stop calling and if they needed to talk to me then leave a real message. Then I got a call the next day and they left a message asking for me by name then hung up. I have now started calling them several times a day leaving messages about how stupid they are but no one ever answers. They are starting to really piss me off.
