POOR COSTUMER SERVICE AND BAD ATTITUDE

I went to telkom mobile Sandton on the 21st to upgrade my phone everything was done and l was approved for a samsung galaxy note 4 , the consultant then told me l must wait for his call because they don't have stock in store. I called them a week after still they didn't have stock but they advised me to take my application and go to a telkom direct store in fourways crossings or Rosebank . I went there on the 3rd of Sep which is today when they checked with my ID number they advised me that everything was done and their systems indicate that l collected my phone today therefore they can't assist me l must go back. I'm here in Sandton they still insist that they can't help me, the device has been discontinued meaning they won't receive any stock for it. I'm so frustrated yet still confused how come they finalised my application? Now my upgrade has been messed up and l must pay for something l don't have.
