Bad cudtmer service Gsm/vodacom store workshop Durban

On the 26 /02 / 2020 I took out a new contract with the Gsm shop in the workshop Center Durban next to the Vodacom shop. I had said I do not need a new sim as I had already had a vodacom sim card which was in my tablet and I would like that sim number to go in the new phone. This was done. However the next day when I had called Siddeek with regards to the R175 airtime which I had not received he had said he called vodacom and they had advised him that I had already used all the airtime. Which I argued as I had not used the phone I had not learned how to unlock or work the phone properly and I was such that evening due to the flue I had gone to bed very early. Siddeek however insisted I had used all the airtime I requested a print out upon calling the number I had allegedly called I fined that the calls were to people I had not know proving I had not made use of the phone nor the airtime. At this point Siddeek then calls vodacom customer care only to find my number had been given to someone else. I was also called by lanette from the same gsm vodacom store who told me she was going to block my vodacom number which I had requested to be used in the new vodacom contract phone and her reason for this being there was two people using one number and the other person had used the number for longer than I had. I then called vodacom head office I had to explains what was told to me by lanette from the gsm vodacom store in the workshop centre. The call centre agent asked me for my details and advised that my vodacom number which I had taken on the 26/02/2020 had been removed as contract on their system on changed to prepaid. The call centre agent asked me who gave the authorisation for this to be done I had said not me. As far as I know I had taken and signed for a two year contract not a one week contract. I was also advised as of the 1st of March 2020 I will not be receiving the R175 airtime as I had signed for. This has been the worst customer care I had ever experienced I am very disappointed in the gsm vodacom shop in the workshop centre Durban. I wish I had never walked into the store as they have been nothing but trouble. I do not want the phone anymore as I have not even used it due to it being blocked and unblocked and now blocked again. I would just like my vodacom sim card back and my number please
