Very poor service delivery

I recently upgrade my contract with Autopage Midrand. It was a router/TV combo deal. Its been three weeks and I only had the router delivered to me. I have made numerous phone calls to auto page, to find out the delivery date of my TV. Last week i was told that they would be receiving stock of the TV's on Friday 20/03/2015 or Monday 23/03/2015, and that it will be dispatched for delivery immediately. I called today to find out if it has been dispatched, only to be told by the operator that all TV deals will be escalated to a manager and that i will receive a call later with feedback. I am now tired of hearing excuses. If you guys don't have the stock of items, then you should not advertise that item. I am shocked at your poor service delivery. I would expect this from a smaller organisation.
