Man that sounds like a terrible experience. I'm actually not a fan of what all the couches are allowed to do in my league, but, verbal only would be very frustrating. Also, three time outs a game? At that point you're not even playing your opponent, you're playing the couch. My league is in fact APA. I've used my technique at least once every league night, during playoffs, during cities, I've never been told it's not allowed.
I don't believe there's a rule forbidding it, unless it's something on the local level specific to your area
