Unhelpful call center and wrong product delivery.

I ordered a charcoal colour Curtain and paid 50 for delivery. I got a grey curtain instead. I called and your agent was unwilling to help as said I should WhatsApp. I received a reply indicating they would investigate and get back to me. She ended that chat while I still had questions. Rude. Then I reached out on Facebook and you simply told me to take it in for a refund. I paid for delivery so that I did not have to go to a shop. You should deliver the correct colour and take this one back. The photo on the website and the photo I sent you is clearly different colours. Now I must go ask for refund and won't get my delivery fee refunded. This is not fair.
