Cell C a *****

In April I cancelled one of my cell c contract then was told my last debit order will be in June, come the beginning of June I get a call from cell c the guy was telling me how I was one of their loyal customers and they had a mother's day special two phones for the price of one. I then asked that can the person using the other phone use any other network his answer was yes, the phones got delivered. When I opened the package I saw two other sim cards then inside each phone a sim card too, I only used one sim card that came with phone. Come the middle of July I get an invoice for two sim cards, a 5gb pinnacle and a 2 gb pinnacle and already I have a 2gb pinaccle and a 10gb pocket router contracts. I called to cancel now I'm being told I agreed to both sim cards and if I wanna cancel I must pay R4285.. I feel cheated and de*****ed as a client of over 10 years with cell c. How can in these difficult times agree to two other contracts as an individual how can I have four contracts that's insane. I'm really not happy and feel that Cell C is taking advantage of its customers and along the sales conversation they add things and misled you when initially you asked how much I'm paying I was told R499 for two phones now its about R1500.
