Vodacom bad service

Hi in November I went to apply for a contract gave all my details I'd book proof of income and so on. Just to be told later that day that I was doing ***** by the sales rep to my shock I could not understand who I was **********ly de*****ing as i would be de*****ing myself and was told that they wanted to run a sting operation on me 2 weeks went by with no word from them. Get yourself ready for this I receive a e mail saying that my contract has been activated and I must enjoy my contract. What contract as I never was called or received a e mail to tell me that it was approved. So I went it to the store and was told that the device was delivered by the sales guy in store to my house that I never received so they replaced my head set that was ****** by some one else in the street that it was given to by the sales guy from the store please keep in mind this is a s8 + the phone I had given to me was just a normal s8 now when I went in I asked for a contract under R1000 rand then looked at my bill 2500 I have not used the SIM since a received the phone as all of this is just to fishy and I won't deal with the store no longer thanks Vodacom for messing up my new year stay away from Vodacom you will have documents go missing I have not even got a slip for my phone even worse I was not even told how much this contract is as it was not what I had agreed to only to see a bill that I have been charged double for been made to feel like a ******** by them. I earn a good pay every month watch out for Vodacom you will be left feeling helpless I now have to get a attorney at my experience to have this fixed
