Return my funds in full

My company gave me a letter of appointment in agust and requested me to pay the ffc, when I told only realty ballito that they are aware that I have been sick, the entire time and could not practise, they insisted I pay the ffc R2929 and R845, now this is a lot of money. 4 days later they called to say I am no longer needed as no sales produced. I requested my money back they will only refund me R1700. However I have never practised. I was diagnosed with a heart condition this they were aware of. These people are only taking money that is distributed between property practioners. This is the most greedy company.
