I have had 40 units of Botox in my glabella in the last 3 ish weeks and still have full movement. (Photo)

Thanks for this good question.  Only a single photo is available to me for examination, so I will speak in generalities.  If the best explanation offered to you by the injector is that the Botox may have been injected incorrectly, this may be an indication that a second attempt by another injector may be beneficial.  I suggest that you find a competent physician, and tell your story, so that you can achieve your goals.

I am assuming your 'practitioner' is not a board certified dermatologist, plastic surgeon or head and neck surgeon.  You need to see a specialist before you assume anything.  There are many possibilities such as:
Your movement is actually much less than you think (photos would help) and thus your expectations are not reasonable
You were not injected with 40 units of Botox.  This needs to be clarified.  A board certified physician should have some answers for you.
The depth of injection will not account for 'no response' with so many units being used, and presumably charged for.  
You have blocking antibodies interfering with the Botox effect.  Some patients have such antibodies,  which can be tested for at least in the academic environment, yet paradoxically  still respond well to Botox.  Therefore, it is not a perfect test.  If a patient is documented not to respond at all to 40 units of Botox which was properly placed and injected by a reliable physician then such a test might be useful.
Changing products from Botox to Xeomin or Dysport might sometimes help a bit but a no response to 40 units of Botox is so rare that there is likely another explanation. 
There are many fine board certified and academically oriented dermatologists and plastic surgeons in your area, including the academic departments of the many respected universities near you.

For frown lines, 20 units of botox is the standard dose.  I may do a little more for my male patients who have stronger muscles but 40 units seem excessive.  In terms of placement, botox does not require "deep" injections as it selectively targets the muscles in the area.  Consult with a board-certified and experienced cosmetic dermatologist.
