Fed Up and unsure of contracts that I have not app**** for!

My story begins on Sunday, when I was pick pocketed in Shoprite Watergate. I called to cancel or blacklist my phone and block my sim card. All went well. On Monday, I went into Cell C and did a Sim swop which was sorted without hassle. On inserting my simcard into a phone later that evening is when I was alarmed. After all my messages came through I noticed a message that read, " OTP number ....... Your Cell C contract is almost approved. Please call, 084 151, option 1, if you did not apply, Cell C." Immediately I call the number as I did not apply for any Cell C Contract/s. No luck as it doesn't have any options as stated in the message and it doesn't allow anything else but asks for a SSID, which I do not have. After about 3 attempts I decide to call Customer care. I was helped by the agent and explained that all the departments that deal with that is closed I should call back Tuesday and should try 084 145. Tuesday, I call 084 145 and I have yet to be helped. Number keeps on repeating the options and once you select your option it waits and then it kicks you back to the general number. After trying numerous times I decide to go through to customer care thinking they probably having a technical issue with their lines. Okay so I explain my issue and the agent explains that he cannot help me but will have to put me on to the contracts department, here I have to explain my situation again and am told I will need to go to a different department that can track and cancel the contract if needs be. The agent transfers me to a line that tell me ' the number you have dialed does not exist. ( So being a call centre agent in my day, we had to transfer the customer /client and explain the situation and then go back to the customer/client and introduce the agent on the line and then hang up) but that never happened I was just shoved to the extension and left to fend for myself. I tried calling again and went to Customer care as I now knew the line was not working. I had to explain my situation all over again. Only to know that I would need to be transferred so I asked to be escalated to the agents senior, who then helped me and transferred me still to the next department where I had to explain again. The agent then told me he will put me through, I did for my own sake ask what is the number to dial if I were to get cut off by any chance and then he was going to transfer me. He did so but not to the next department but to the rate the service line where I realized that my call had been ended. My query is still not resolved. I am not sure if I will have 1 or 2 contracts on my name that I never app**** for and I do not know what to do from here on out. Extremely irritated and frustrated at this point!!!!!
