No refund for ucount rewards

Placed an order on the 6th of February for roses to be delivered to a business address on the 14th of February. Come the 14th, and by 3pm, the delivery had not been made. Contacted them, and was told that delivery would be before 5pm or at 5pm. I contacted my partner and told her that she had to wait at work until 5 (how embarrassing). 5pm came and went. Contacted them and they said that they will deliver before 7pm. 7pm came and went so I canceled the order. Valentine's day was over and I didn't want my partner to wait like a fool for roses that probably wouldn't even come. My partner was contacted after 7 by the driver, saying that he is still busy delivering in an area 30 minutes away. Lucky I canceled. The problem now, is that Netflorist doesn't want to refund me. I paid using my ucount rewards and they say that they can't do a refund of ucount rewards, they can only credit me. Basically forcing me to buy from them. Why offer ucount rewards as a payment option, then? My cancelation was due to Netflorist not honoring their agreement by delivering on time. I paid premium price of r900, I expect premium service. With all of this, i did explain to Netflorist that I understand it was a busy day. However, they took my payment and now need to do right
