Complaint of dissatisfaction

I placed an order at home choice and I explain to them that I will fetch it myself at promenade and the person that I spoke to said no it's fine I don't have to go all the way to promenade I can collect it at any clicks store bcz I told her that I don't want to pay the delivery fee that's the reason why I want to fetch it myself. Now when I check the invoice there is a delivery fee of R186 can you please advise.. Because I am planning to refund everything and close the account bcz I am really not satisfied bcz I don't why she **** bcz I was willing to go to promenade bcz I'm working that side in the mall
