Really annoyed as NOBODY can give me an answer.

I've been a loyal vodacom customer for many years and it saddens that I now have to resort to this to get an actual response from Vodacom. On the 26th April i did my latest upgrade. I specifically went for the Sony Xperia XZ1 with the option of taking a PS4 for an addtional R49 per month. The only reason i took this upgrade was for the PS4. Now i have the phone, but I have yet to receive my PS4. I did the upgrade at the Nelson Mandela Square vodashop in Sandton City. I was first told that it will take a week to receive the PS4. The 3rd of May came and still no PS4. Then I was told the 10th of May. Still no PS4. I've been sent around circles as nobody can give me a definitive answer as to when I'll receive my PS4. What really annoys me is why advertise the package BUT have no stock available. That just blows my mind. Nobody has thought to call other vodashops to see if they have stock. Nobody as thought to just go to any CNA, or Musica store purchase a PS4, give it to me then when the stock arrives keep it at the warehouse. NOBODY is able to give me an exact ETA as to when stock will arrive. i've been pushed from pillar to post and still no answer. Nobody is able to help me. I would appreciate if someone from head office can contact me asap and give me an actual answer. Better yet, someone is welcome to go buy a PS4 for me and deliver it to my office in Sandton. Even more annoying is my first instalment has been paid. So in actual fact i'm paying for something I don't have.
