Lying to make sales

I have had a cell c contract for almost 15 years and this is the first time i ever get such service. When I arrived at Cell c n1 city on Monday 06.11.17 I was assisted by Kadeem.I asked the gentlemen to check if I am due for an upgrade.He took my details and told me I can upgrade today if i want. I then asked for the options of phones I could pick for the package I'm on..Kadeem checked again and informed me I'm on a top up contract and that I could either pick between the P10Lite 4 R299 or P10 R599 or even a LG R249.. I told him I dnt like the LG so tell me about the P10 & P10 Lite he explanined the phone features to me and I asked if there was enough stock for both P10 phones he said yes there is stock.. I decided to take the P10 Lite at R299..Kadeem brought me papers and said I can sign papers and then he went to get the phone only to realise there is no stock as it wasn't delivered yet.. I asked him why he said they had in the first place? He rep**** by saying that he didn't know the stock never came in..he then told me he will call me on Tomorrow (Tues 07.11.17) as soon as the stock came in...The next day came and no call so I went to the mall to follow up with Kadeem and still he said the stock didn't come and he would call me the next day when it came.. I got a call at 10:55 the Wednesday from Kadeem to say my phone has arrived he will active it and when I come in later to the store we can open the box and set the phone up for me..I told him I'm not sure what time I finish work but I'll try and make it before they close.. He said he will be there till 7 so it's ohk..I then asked him if it was the P10 Lite for 299 on top up and he said yes as we discussed on Monday and I ended the call... At 11: 49 Kadeem called again to inform me he made a mistake and that the P10 Lite wasn't 299 that was a different contract package.. He then rudely told me I can have the 299 but then my entire contract will change from top up to straight up..I informed him that he confirmed everything with me so why only 2 days later do u realise that you made a mistake..His reply was cold and rude and I was told that if I dnt wanna take the 299 on the other contract then their nothing more he has to say to me and hung the call up in my ear.. I called the manager on duty Navaria and explained what had happened she said she would speak to him and get back to me..She called me back to say that Kadeem said he never told me the phone was R299. I asked her if the calls are recorded as Kadeem called me twice today one to tell me the stock arrived and the second call is to tell me he have me the wrong prices plus I signed pages when I was there monday ..The manager asked Kadeem while I was on the phone if what I am saying is true that he called me twice and he told her No he never called me.. I was shocked as everything Kadeem told me to make the sale was a lie and now he tells his manager I am lying.. This is the worse customer service I have ever received and the manager said she will discipline him for his actions and she is sorry for what happened.. i called the call centre and asked what i could do as i was promised a phone for 299 and being told i must pay more..Kholowe at the sales at head office explained that the manager needs to honor the price that I was given and if not i must take the matter further..If this is the standard of cell c then I'll rather find another network to take a contract with..
