misleading information

I call the clientele mobile call center \RMCS"on Friday the 13th to request a sim swap then I get told that they will refer my query to their admin department and this will take about 2 to 3 days then I tell the agent that I want to cancel the contract as it had already expired and I was on a month to month contract. She tells me she'll cancel it then I'll be able to do a sim swap directly with Vodacom. Monday I call Vodacom then I'm told that my number is still with clientele then I call RMCS again on Tuesday and they still tell me on their side it says canceled then again on Wednesday and I ask this lady what I should do then if vodacom says its still with them she tells me I must wait till 3. Why the hell should I wait for 5 days for my own number to be swapped because when I took this contract it was just for the airtime not that so they control my number as well because now this means that they own my number and there is nothing that vodacom can do as they cannot see any data from their side. I'd like to warn anyone who wants to get a contract with RMCS not do do that as they mislead people and tell them its just for airtime meanwhile they take ownership of our numbers. """
