Sim cards

Mrprice Group and Miladys charged me for a sim card that I did not agree to pay for. They informed me that I would receive a recording to confirm that I had agreed to pay for the sim card but I have not received the recording to date. The amount I "owed" them was R480.47 which I decided to pay because of my credit record. From now on I will never agree to such "promotional sim cards" that I know nothing about or have little info on. I regret even speaking to the consultant about the sim card because I was unaware that it was a contract. I just had to voice my concerns to assist someone who may encounter the same issue in the future.
