Failing to deliver and lack of communication

I opened a new line contract before the 6th of September and it was approved on the 6th which I assuming was a process issue. Now the problem is that when I placed this request, I asked about stock and I was informed that stock is available but now on the 13th after countless calls, someone was honest enough to inform me that stock was an issue which now is an inconvenience to me because I would have bought it else where. I called Cell C clearwater to find out if they have stock and I was told they can help and stock will arrive Tuesday and when I call today, no stock is available. The issue here is the communication and the lies that I keep receiving from the team. This was an application from 30th of August and where are we now?
