Charged for Sim and Connection fee after being advised I wouldnt

<p>I went to the Telkom store in Fourways Mall and was assisted by a Gentleman named Zak. I had a prepaid sim card that i brought with me which i wanted to convert into a 5 gig sim only, month to month contract. I brought my own sim to avoid paying these fees. I gave Zak the sim and he advised that it was not necessary as he can give me a new sim card and i wouldnt have to pay any Sim and Connection fee. Now i have recieved my invoice for the month, and i see R200 sim and connection fee has been added to my bill and i am going to be debited this at the end of the month. I did not agree to this. And i was **** to by the Telkom consultant. I will cancel the contract should this amount not be refunded/removed from my statement. </p>
