Agent dishonesty

I moved out of one of their properties a month ago. I spoke to my agent regarding this and I was told I wouldn’t be able to get all my deposit back because I terminated my lease before it ended. Which I understood, however, I still haven’t been refunded. Whenever I send the agent a message she always says she will get back to me and she never does. When I call her she doesn’t pick my calls up. This is very upsetting concidering that they never struggled with me as a tentant. I always paid my rent on time and I paid my key deposit on time. I am very disappointed and upset.
