Just property unfairly treatment

I have never felt treated so low in life like the treatment i got here. I have a contract with them from the 1st of jan 2023 ending 31 December 2023. The agent didn't send any communications during November like what i am used to to find out if i am renewing and let me know if the rent is going up. Saturday the 30 of December when driving out of the complex i saw the agent and she asked me if i am renewing i sad yes and she nothing about the rent i thought everything will be like of 2023 i paid the usual rent then on the 5th i received o notice demanding high rent from the usual i rep**** to the email with my story that's when the agent came in to communicate by that time she is giving me an option of moving out or pay the new rent i tried looking around to find an apartment but i was late most of the apartment were taken December i was only getting bachelor within my budget I felt treated so unfairly
