Service has not been delivered after 2 weeks

I have app**** for the SmartBroadband Uncapped Wireless service on 2 March. I was contacted on the same day where I had to verify all my details and sign a verbal contract in a sense. I was told that the device and sim will be delivered within 5 - 7 work days. It has been 2 weeks now and still no contact from them. I have tried contacting them through Twitter, calling, the on-line chat service they have, their community forum and each time they can't tell me anything about the progress or status of my delivery. I am extremely frustrated at this moment as my brother has ordered the same service 7 March and received his device on 9 March. So I can not understand why mine is being delayed and why no one at all, through all their channels, can help me or tell me what is going on with my order. I have been told it has been escalated and I will be called and still no call. A bunch of empty lies just to keep me at bay. This is unacceptable I would have thought a company like Telkom would actually deliver a good service and keep to their promises.
