This is Mediacom calling with special offers. They will keep calling until they speak with you. The key is to let the recording go all the way through then wait for the sales rep to come on. At that point you can tell them never to call you with a promotional offer ever again.
I keep receiving calls from this number. Every time I pick up they hang up. I had to use star 69 to find out who it was since I don't have caller ID. Why would somebody from Mediacom hang up on me? Whatever. I least I know who it is now.
