The response was just not justified

Uum in my life of renting, I have never encountered this. After seeing a property I was interested in, I quickly submitted all the paper work with no time to the agent. 2 days later, the agent requested for additional bank statements of which I supp****. A day later she phoned requesting us to sign an aditional document which she said the owner had taken Rentsecure as insurance against breach. Little did I know that rent secure does not like foreigners to occupy their clients premises. They requested a double deposit on the property. I have not heard of double deposit if by virtue of your documentation you are a resident. Paying R21000 plus additional fees to occupy a flat for 7000 per month is just ridiculous. The director of rentsecure wrote an email stating that double deposit was only required for pple who have their own businesses and or self employed not because of being a foreigner. But they still denied the application on new grounds that my husband got a new jod & is on probation for 3mnths. This is a permanant post people. No one is willing to give us answers of exactly the reason for this decline. This is unfair, I have not seen such ************** in my life.
