refund refusal

I want to give avon zero stars. I was selling avon for about 5 months and after many issues I decided to stop. I have a small credit on my account and after two months of too and fro it is eventually at a point where i should get my money. Now i keep getting emails to say that they cannot refund me as the amount is less than R100!!! I dont care about your inhouse policy. You owe me money so pay me back. What more must I do. The amount is almost R53....sorry but it is the principle of the story. If you do everybody in like this then you can pocket a few bucks in a month. Just refund me please!!!!
