Keep a record of the dates and times you'd called? When you actually see that doc? Just hand him a copy listing the # of attempts you made.
Keep it up. Be relentless.
Often these 'assistants' are called 'nurses'? But you and I are likely as qualified or more? They're glorified gatekeepers.
So, let your doc know you aren't very happy about this 'issue'.. start looking for alternatives [unless you've gone thru the 'list' already].
Good luck to all!

PLEASE THO? No more 'stinkbug talk'? You're giving me the willies! They're even HARD to kill.... ICH.
