No refund and no feedback

I had ordered a Huawei tablet and the R90-00 debited off my account on 27.02.2016 and emailed to check the status of my order on Thursday 03.03.2016<br> I received a call from Roxi , Friday 4 March 2016 at 16:22, 16:49 and 16:52. During the first call, I was told that she was going to check on the status of my order and call me back. A few minutes later, I was called and advised that there is no stock of the 8GB SD card. I was asked if I wanted to cancel the order. I advised the agent that I do not want the delivery without all the accessories and I do not want any issues once I open the package. Roxi told me that she will cancel the order and refund the R90.00 admin fee that was debited off my account. She confirmed that she will cancel the order<br> I received a third call from Roxi, advising that I should reject the delivery from the courier, if they deliver it. i emailed back to request written confirmation of the cancellation, the refund to be made, that I will not incur any additional cost for rejecting the delivery from the courier and that my account is not going be debited in future. I got no feedback and no refund as promised. I emailed again yesterday. Please sort out urgently.
