Cell C Delivery

I ordered a iphone 6s plus from cell c last week, over the phone all went well and the guy told me i am approved and i will be getting the phone this week still nothing i called this week tuesday to do a follow up, they still did not send it for couriers and told me i would get it friday at the latest i gave them a call again today thursday just to follow up how far they are, then the lady told me its still not send for courier and that there's no stock. The one clerk says one thing and the other says completely different, I'm going to cancel my contract with cell c this is not the first time i had a problem.
