Hidden and extra costs on Edgars Account not cancelled

I opened an account at Edgars Brooklyn a while ago and saw on my statement that they have added an Mobile Content Subscription of R59. I don't know what it is for and no one can tell me what it is for either. I have cancelled it on 11 July 2024 just to see that it is still on my statement this month and has been ever since I cancelled. After holding on for almost 10 minutes they could only escalate the matter to some or other department. This is SO frustrating, it is totally out of my hands and it's not something I wanted or knew about. I will close this account because it seems like that is going to be the only option to get rid of this.
