Haven't received goods yet, but money taken

I signed a contract for a 1G data plan with a free Huawei Mediapad deal with Telkom. I was under the impression that this was a Telkom agent. I was told that I would receive this package in 3 - 5 days. It has been more than 5 days and I have not received the package. Telkom does not have any information of me purchasing this deal and that it must of been done through Selldirect. I have tried phoning Selldirect numerous time but they do not answer their phones. I see money has been taken off my account even though I have not received anything. Also the amount is more than what the deal is. What should I do if I cannot get hold of anyone?
