Where is my contract signature????????????????

I recently went to a Cell C store in South Gate to try and do an upgrade on a data package I was on. The contract had expired. On the day I decided to go to the store I had to abruptly leave due to some unexpected events. Before I decided to leave the store I was sitting down with a consultant that was on hold waiting to be answered by someone from the Cell C contact center to assist with the upgrade. Because we had been waiting for so long for our call to be answered I decided to leave the store and told the consultant to leave the upgrade. I would return on another day when I wasn't busy. To my surprise, I am debited for the month of April. I called the contact center and I am given a number to the cancellations department where I speak to a lovely lady by the name of Seipati who couldn't assist but asked me to hold for a Supervisor. I speak to a man by the name of Brian Tunyiswa who told me he is gonna log a call/complaint with the store to get refunded. And then he says I have subscribed to some content subscription that bills me R170 something (lol) and I need to pay for that at the end of the month (May)???? Haaaaaah??? How when I didnt sign up for a contract to begin with? and he also says I subscribed via a link (on sms or something). How ??? because this sim card is in the wifi router??? OK, I proceed to ask him how this is going to be debited from my account at the end of May when I didn't ask for any of this or signed for any contract...He says to me...exact words "Mam I need to hang up as I have explained that I am going to send an email to Cell C in South Gate. I will also transfer you to customer care to cancel the subscription". So first I get debited for something I never signed for and I cant ask questions. So he HUNG UP ON ME instead of transferring me!!!!!! In a nutshell this guy told me that I need to go through to customer care to cancel what I didn't sign/ ask for and then the call was cut because he hung up. I will not be taken for a ride by cell c, especially when I have NEVER missed a debit order. I was patient enough to be put on hold while people were doing God knows what (cancellations dept). Then I was hung up on and I am supposed to wait for them to debit me again?????? I have never been so angry. @Cell C, if you dare debit my account because of your *********** consultants who HANG UP on people when asked pressing questions you have another thing coming. I will not be billed for your incompetence.
