Terrible service-unauthorized charges

I opened a Makro account in March which is done through RCS. After opening the account i got a call from Makro offering me a R500 voucher for cellphone accessories "for opening a new account". A few weeks passed and I received the voucher via sms, however i never used it. Since April I've been charged R299 for Blue label subscription four times on this account. I've sent numerous emails to both Blue label and Makro requesting cancellation and refund but nothing has happed to date. I asked Makro who gave blue label permission to put charges through on this account and they could not give me an answer. I want the charges reversed.>>>>>>>2 weeks later after emails going up and down between myself and Blue Label they are refusing to give me the copy of the phone call that they allege i agreed to the subscription and are refusing to refund me. RCS/Makro is also now not responding to any of the emails. I feel that they need to take responsibility to ensure that myself and them get access to the recording as they gave Blue Label access to my account to put through subscriptions. A total of R1495 has been charged on my account. When giving Blue label the call reference numbers from when I started to query this they are now ignoring my emails (both Blue label and RCS/Makro). I will pay off this account, but i promise you I will not pay for these charges.
