Terminated contract

I have a cellphone contract with Telkom and then I app**** for 2 more contracts on the Sony M4 Aqua duel sim. When the phones arrived, I showed the agent at Vanderbijlpark Telkom that this was not the duel sim devices. She told me that the duel sim devices has been terminated. There and then, the same day and time, the contracts has been cancelled. Ever after since, I kept on receiving statements for the cancelled devices and every month telkom withdrew the money from my bank account. I then reversed the money and sent the payment for my currant contract via EFT. My currant cellphone account is PAID UP TO DATE. I even kept on paying after my currant contract has been locked because of the cancelled contracts. For 3 months I keep on paying for a service I do not have. I then received a sms from Pinky that the contracts has been successfully canselled. This moring I received an email from Telkom, informing me that my currant contract has been terminated due to arrears and that I must pay nearly R10 000 panelty fees. Please Telkom, please sue me...PLEASE.? I look forward tobreceive a summons from you. And it aint me who is going to pay the lawsuit or panelty.
