Wrong order and bad customer service

I order 3sets of comforters for R999 was suppose to pay an instalment for 12months,surprisingly I received 2 big boxes full of huge heavy comforter and 2 big blankets,so I called the company to ask why they delivered a wrong order and they requested for me to post them back to them and they refused to come collect their wrong delivery when I asked them too.I had to travel using my petrol and had to stay off work just so I can go to the post office,posting the two big boxes back to home choice cost me R800 including my traveling cost it cost me closed to R900 which meants I've actually spent more than what I was supposed to spend as I couldn't afford to buy the products in cash but at the end of the day I ended up spending far more. I don't feel I have been treated fairly as a customer while some of my white colleagues confirmed Home choice collected the product when something similar happened to them.I am not happy at all.
