requesting managers never works, they just send whatever tech anyway. its like asking for a spanish speaking tech...right. the only way to get that done is to actually call his manager if you have the direct phone number.
anyway, this guy probably got dinged with a tc for installing 2 hoppers when the system first came out, becuase it didnt work then. so maybe he's afraid. i can verify it DOES work fine, now. joeys 'hopping' between hoppers is thw hole point, right? you want that capability.
