No stock at all stores

I went for an upgrade on 5 April, I was approved on 7 April after contacting the Kolonnade Telkom store myself. It has now been more than a week that I have been waiting for the new phone, the store does not know when stock will arrive until today when Sithembi Hintsho form telkom head office phoned me for another contract. She confirmed that she has got stock and I completed the upgrade via telephone. she said the phone will take 7 to 14 days to reach me and I agreed. 2 hours later she contacted me again and said that she could not help me any more and put the phone down in my ear. Now how is that for service? I even went across thee road on 11 April to Telkom direct and they confirmed they have got no phones in stock. Seriously? How does a service provider not have stock of any cell phones. How must customers upgrade? Do they want customers to flee to different service providers??
