AIRTIME/DATA SUBSCRIPTION FEE and SMS AIR SUBSCRIPTION

I have an Edgars account and recently I noticed that an amount of R78 for airtime and data subscription and R49 for sms subscription have been added to my account. I have NEVER AUTHORISED this and I am not sure who gave Edgars the right to add this to my account especially since I do not even receive this airtime and data. This started in May and have been accumulating in my account since then. When I went to the store to query this I was told that they will call and cancel my subscription. I was told I would be called back but nobody called. So I went back to the store and was given a reference number and was told I would get called back again. I have been waiting for a week for the call. I then asked if I can close my account then I was told that I cannot until I have canceled my subscription which I never authorized mind you. I was told that even if I settle my account, these fees will still be added to my account and might eventually get blacklisted. My question is how on earth is this now my problem since I have never even asked them to sign me up for this airtime nonsense. And how is it that I now cannot close off this account because of this. I need this subscription cancelled and the OTA so that I can close off this account then I will never have to deal with Edgars. I am very disappointed I must say and feel that Edgars should fire whoever is responsible for this *****.
