Vodacom new contract bought 27th July, had to return phone on 28th July still dont have the phone and no contact from Vodacom

I bought a brand new phone on Friday the 27th of July 2018 from Vodacare Vodashop Canal Walk the salesman that assisted me was Imaan, the whole time while he was renewing my contract he was on his whatts up chatting to his friends of which I found that strange. When he was done he gave me the phone and did not open it to insert my new sim card as I did a sim swam. I then asked him if he is not going to insert the sim card and when I asked he did so. He then gave the phone back to me without putting the phone in a bag atleast I then asked him again if he is not going to put my phone in a bag and the reason why he forgot to do all these things is because he was chatting while assisting me. He then forgot to give my phone pin while I was approaching the door I then told him again that he left my pin at his desk and he went to fetch it. Was not happy with this poor service I then spoke to the Manager who was on duty that day and her name was Stephanie. I told Stephanie of the poor service Imaan gave and I told her as well that I want her to check if my new phone is working properly because my previous contract P8 Lite Huawei had a problem for the past 24 months I did not have wif and still that phone cannot connect to wif so I asked her to make sure that this one is working before I leave the store. I was then advised that my sim card will only work the following day I then told her that I will check my phone in the morning if it gives problems will come back.

On Saturday the 28th of July I returned back to the store because my new phone was not working I spoke to the Manager on duty his name was Pierre they checked the phone and discovered that it is not working and it has to be sent for Software upgrade and I would have to wait until it returns don't know when. I was so angry and told them how can a new phone be not working it doesn't make sense and I was told they will call when the phone returns.. Today it the 2nd of August and I haven't heard anything from Vodacom which means I am paying for a contract that I am not even using now I am sitting without a phone.
