We pay for things we don’t know

Tfg pls tell me why u always add money every month to my account.last time I checked was owing R900 now it has grown to R1700 in 2months.I keep on paying but u keep on adding things i don’t even know.I went to the store today only to find out I’ve subscribed to things i didn’t even agreed to.Magazines?who said I need that.You charge R40 to send an email and that time u send even useless emails for you to be able to charge extra.I need you to cancel those things all of them.Once I pay this R1700 of yours Im closing this account.I can’t be paying for things I don’t know.Fix this!!!!!
