Misleading client !!!

I have been billed for a SIM card that I have never used before

The company that sold me SIM card are aware that the consulted that have assisted me to buy the sim card has misled and gave me wrong information about the SIM card hence it resulted in cancellation

I have never used the SIM card before and I have all the proof where the consultant told me to reverse the money and buy a small router knowing very well that it still won’t work

Apparently the SIM card needs a big router which I was being told after I got the SIM card

I find it unfair that I have to pay the cancellation for the error which where done by the company not me and they have agreed to pay the cancellation fee, lady who was handling my dispute in that company

Please note I have never got the call and Vodacom is not even replying my emails Whilst this is affecting my credit score
