I have read this for so long, I will give a short opinion.

Regarding the March 19th cut off..

On one side, Latinpass shouldn't get so technical on the exact cutoff time unless it results in some extraordinary amount of hardship on Latinpass. I can't see why a company would be so picky as to a few hours or even a day or two. I believe that businesses should always have an undisclosed built-in grace period.

On the other side, if you signed up for Latinpass and Latinpass promptly notifies you that they are not going to except you, that is their right. A business does have the right not to do business. So, if Latinpass won't acccept you, that is about all there is to it. Now if you purchased your tickets with the agreement you would be credited by the Latinpass promotion, that is different; but, if you aren't out any money from ticket purchases, I don't see how you can force the issue.
