Laughing behind customers back, so NOT cool!!

We went to the Menlyn Musica and had excellent customer service, we were looking for a specific DVD and they phoned around and got one at the Gezina branch. They organized that one be kept for us. We went there a bit later in the day and got smack bam rudeness in our face and at our backs. The DVD was sold. It will take 2 - 3 weeks to get another one at the branch. They did not even phone one of the other branches. I then complained about the fact that it was not kept for us and that they did not phone us to inform us that it was gone, I turned around and the manageress laughed at my back. She and her *********** collegue smirked at us the whole time. Unfortunately we have to go back to Musica as we received Musica vouchers and unfortunately it is not refundable. I am so disgusted in this customer service
