How do you get the trade in code for the $100 gift card?

Question

On January 28, I activated a Samsung S4 that I had mail ordered from Verizon Wireless.  I went to the online chat service to find out about the $100 trade in for my functioning Moto Bionic, and after some back and forth, was told that they could not help me and I had to call customer support.
I generally prefer not to call because of the waiting time, but on several of my calls on this I have actually gotten through fairly quickly (i.e. under five minutes of wait).  So, on the first call, I was told to fill out the form on the trade in page using the code "Smart100" where required the online form.  The "Smart100" code did not work (and I tried various permutations, including initial cap, initial non-cap, space, no space, underscore_connect, all with no success). 
I called back to inquire why "Smart100" did not work, and after the CSR explained case sensitivity to me (and I explained all the permutations that I had already run through before calling back), we agreed that Smart100 was just not going to work.  She then went to find further information.  She returned to the line to advise me that, indeed, Smart100 would not work, but that Verizon would send my phone a text of the code to enter on the trade in page within five calendar days of activation of the new phone. 
I called on the sixth day, and I spoke to another CSR.  She told me that the five calendar days was inaccurate, and the code would arrive on my phone within five business days. 
I waited until COB on the fifth business day , and called again.  However, the CSR (accurately) pointed out out that it was not yet midnight, and  the code would surely arrive that evening. 
Unfortunately, I still (some 2 1/2 weeks after activation) do not have the code.  I have decided to try a different approach, to wit, a posting here. 
Suggestions?

For whatever it's worth, I received an email back in the same day from the "Wireless Device Recycling Team" with a code that went through.  I am not sure who the Recycling Team is, but this was a very positive experience after the frustrations of talking and chatting with CSR's who, while trying hard, were not well informed about this particular issue, so hats off to the Recycling Team.
