No delivery since September 2014

In September 2014 I ordered a phone, cover, screen protector and 64GB SD card from the Orange online store. Although I qualified for a free delivery, I opted to collected my part shipped order (phone, cover and protector) from the Orange SA warehouse. I was never contacted about the status of the SD card, and despite numerous attempts to get feedback using the e-mail address provided on their website, all I ever received was the automated email response. I have called the call centre numerous times and I have been told that the SD card I ordered is no longer available. Each time I am told that they will escalate and investigate, but no one ever contacts me again. I called again yesterday and the call centre agent then asked me why I didn't resolve this in September last year already! After consulting with her colleague about the actions taken to date, she then offered me R150 voucher as they could not provide the SD card. A R150 voucher in return for a R480 order that was never delivered? Do you think I am stupid? The lack of after sales support, customer service and feedback from Orange is shocking. I would strongly caution anyone against buying from their online store!
