I totally understand your position... I had a partner (who was also my faince) who was a wonderful WONDERFUL dancer with a good lead, it was subtle, but he made sure you knew what you were supposed to do. Well, he died in an accident about a month ago and now I am dancing with a Newcomer (I am at the bronze level). He has stepped on my feet countless times and doesn't know how to lead AT ALL! Specifically, he won't move his body to give me the least idea of what he is doing so I think we are continuing basic and he will just go off into his own little world and do something else (normally ending with him crushing my feet). He asked me the same question and I told him that I wasn't feeling his lead at all and that I had no idea what he was trying to do. Later that night, he started to brag about how good he was doing and I had to bring him back down to earth... I hate to say this, but sometimes you just have to literally stop dancing and say, "What are you trying to do?!" They'll eventually get better... and if they don't, you're just going to have to find yourself another partner. Good Luck!
