No Device, no service, still billed. No answer

I looked into getting the R599 LTE deal. Signed up and a helpful telkom sales agent contacted me within an hour of submitting. They asked a few questions and when they will bill me and that if its approved they will have an agent call me in 48 hours to confirm.<br> No one has contacted me since friday. I got billed R599, yesterday 15/09/2015 even though i asked that i get billed end of the month. Now i still havent received any device, any sim, any feedback. I litterally held on the line for longer than an hour and a half and still no one answering. <br> All other departments pick up quickly but none of them can help. The one department i need, isnt answering.
