Do not call him over and over again man trust me. As I have people call me for this kind of thing, its gets extreamly annyoing and stressful when you dont have weed or your busy and the same people just keep calling and begging you, and if hes saying hes gonna call you back..he just might forget? dealers typicly have alot of people calling them and they last thing on there mind is calling back somebody the next day for like a half quarter, think about it from the dealers point of view, if he is out of weed then he is hurting way worse then you, atleast you dont have to deal with hundreds of clientile calling you begging for smoke man.
