Refusing with my deposit and admin fees payment

I app**** for an apartment and paid deposit and admin fees to secure then the agent told me that owner wants a higher compared to the one advertised and I informed that I will not ahead with leasing the apartment. The agent then informed me that I would be refunded but it's been weeks now without getting my refund and I told them I am looking at other places which need a deposit but still no deposit and I am loosing places because of this.
