Not good service at all

Unfortunately De Fraai Diena success has gone to their head. I ordered two pairs of shoes, which they mentioned is in stock and I paid for it. After a few hours they mentioned it is no longer in stock as I presume they allocated the pair to another client and then requested I choose from other colors, we agreed on Denim. But again after a few hours they again mentioned they are out of stock and allocated a mint pair to me instead. Although I have to agree the mint color is a beautiful color and listed amongst the ones I like, it is not practical for every day wear, which is what I was looking for. However, they put this color in my box without me confirming I am happy with it. I requested a different color, but they suggested a refund. I then tried to phone them twice, because I was feeling we were miscommunicating. They didn't answer. I then requested that they keep my money and shoes and we will sort things out after the rush of the sale. I would rather pay the full price and get the color I want than paying a courier price twice and absorbing the banking fees, to which they rep****, they are not going to find my shoes, they took the mint out and will send me the one pair. Basically just ignoring my request and doing as they see fit, without confirming with the client, not to mention the way I was treated by allocating the agreed color to other clients TWICE. It appeared that I must be thankful I am getting a pair. Really arrogant and not good client or business s****s.
