Failure to deliver new phone.

My online application was approved and I was told I'd receive a call for delivery within 24-48 hours. It's been 7 days now. I've sent emails to ********** all of which have gone unanswered. I've called in to the call centre and nobody knows what the problem is or who I can contact for assistance! So Telkom has billed me for a product that they have not delivered! Where is my order???
