I just called the Mediacom support line to find out when the free preview starts for HBO and Max. The answer I received was "I'm sorry sir but we don't exactly know when the free preview starts, sorry.". So I stated the Mediacom doesn't know when their own free preview starts. She (Marta) said yes that is correct and she said I was one of very many callers asking that question. So when I call in to ask Mediacom when it starts, the answer is Mediacom doesn't know? Seriously? Can someone monitoring this please help me out by letting me and others know? Thank you.
