Poor Service and wrong information provided

Reference Number # *** I took out a contract with Cell C for a Wifi Router. I specifically asked the consultant to please cap the monthly useage to the monthly subscription of which I signed up for and not to have it as an open line. To my detriment Cell C went to do the exact opposite just in order to gain more out of me as a paying customer. on the 1st of September I made contact with Cell C @ 10:39am to query why I am paying almost double as to what I signed up for, and that consultant told me that there is some service that someone subscribed to on this number. she then assured me that she will cancel this subscription. she then also advised me to take out the sim card from the router and then dial a *130* number to cancel this service. She said that these services will be cancelled, and I can expect an SMS before the day is over. The weekend went passed and I did not get any sms that this service is cancelled so I phoned Cell C again Tuesday 05 September @ 15:30pm this is where I got contradicting information, where this consultant then told me that whoever told me that is clearly not the truth and that my line is open that is why I am gonna pay more. I advised the consultant that this is not what I signed up for and that I would like Cell C to pull the original recording where I signed up for this and this consultant then starting to have an attitude with me. I advised the consultant that I gave her a chance to speak and that I phoned her and not the other way around and that I too have to say what I am experiencing but she told me she was not present with the previous consultant and what she told me. I then asked this consultant to please put my account on a cap as I am unable to pay more than we agreed on the contract then she told me I must phone back on the 1st of October in order for the cap to be placed on my account. Remember I phoned on the 1st of September, and if the consultant was providing me with the correct information, I would have asked her then to cap my account as per my agreement with Cell C. The consultant I spoke to on the 5th of September then told me there is nothing she can do either then to log a query in order for Cell to get the recording and to then call me within 2 days. Today is the 2nd day and I did not get any feedback from Cell C. All I am asking is for Cell C to be professional enough to give me the service which I am paying for. I am not asking them to give me these services as charity, but I pay every month without fail, for this type of service.
