EDCON GROUP, JET STORE IS EXTREMELY BAD !!!!

Good day EDCON GROUP, JET STORE IS EXTREMELY BAD !!!! PLEASE PEOPLE BE CAREFUL TO CHECK YOUR MONTLY STATEMENTS THOROUGHLY. I am a Jet account holder. On the 27th March 2018 I visited Jet store to close my account with a large settlement amount. I discovered that on my monthly statements they added R41.50 that has been running since 2017 January apparently they added Vodacom cell phone subscription fee of which I was not receiving airtime for. I was informed that due to the airtime investigation my account cannot be closed. However, I paid the settlement amount hoping that automatically the account will be closed without any fees due to me after the investigation. I called for follow up where I was told that they are processing the refund of which will take a long time. Now I cannot close the account due to that which this affects my account since it has started to accumulate fees.
