Poor service from Lucky at incredible connection Greenstone

I received a Samsung Galaxy 8 as a gift wanted to return an unopened box .Brenda from incredible connection greenstone arranged a cash refund as I did not have the credit card that it was purchased with. When ireturned to give it back LUCKY HAD SUTCH A bad attitude and refused to give a cash refund as arranged. The samsung Galaxy 8 46mm is R2000.00 cheaper at a few other stores . Incredible connection dose not do price matching
