Kindly refund my little money!

I placed an order on YST, I was told that 1 item is no longer available, I asked that I am refunded that money as I had to go look for that item elsewhere, this was on the 26th of November. I was told the refund takes 48 hrs. Today the 6th of December, 10 days later, I have not been refunded after several calls and emails to them I was told that the system is slow. YST is clearly for the rich, who are willing to forfeit money when items are not available or have enough money and time to make endless calls.
