What can I do?

I received a 14-day notice to pay or quit on 3/14/2025. Today (03/20/2025) I received a text from the landlord saying I have to pay the full amount that I'm behind on by 3pm today, or else they'll be starting the eviction process. I should have until 03/28/2025 to pay the full amount, according to the 14-day notice.

According to Google, this is illegal. What can I do at this moment? Should I inform them that this is illegal and I'll pursue legal actions if they follow through with the eviction process?

What should I do and who can I contact to get this situation settled, because this is clearly illegal.
