Cellphone contract upgrade fail..

To whom it may concern, on the 13th of April 2018 I upgraded my cell phone contract with vodacom at their Broadacres vodacom chatz center. I app**** for the Sony Xperia package L1 and a play station 4. They explained to me that they didn't have stock and asked me to be patient and please wait. I absolutely understood and agreed to. Every few days I would go in to check if they have my phone and PlayStation ready. Two weeks passed by and on the 26th of April I went in to check if they had my package and I was told no. I asked to speak to the manager and luckily the gentleman was in that day. He made a few phone calls and it was discovered that my phone was in their store room. I was told that the supplier informed them that the PlayStation 4 would be delivered to them at the end of the month. At the end of this week it will be a month since I upgraded my contract and haven't received everything signed up for. When I ask when I will receive it I am given answers like "we don't know ourselves, we can't tell you anything, we don't know anything sorry. We don't know when, we can only wait". It was suggested to us that since they have been waiting but it was only words and very little effort is being made. Would you kindly please help or advise me on what to do to get things done...
