sometimes you have to put some sense of urgency in the matter..kinda like Michael Corleone said to Tom Hagan " are you gonna go along with me on these things I want to do?" Meantime I would be scouting up another oncologist team..you didn say where you were located..that may be a factor before you go scorched earth on them..but remember you are not their only patient and the fact that you are not being tended to prob does not affect their sleep at all...so maybe you need to call them at night at home. ;=)
