Number terminated without consent

As my cell phone contact was coming to an end on 15 April 2025, I phoned Cell C early in March 2025 to cancel the contact and I would like to be on pay as you go, still on the Cell C network. Today I phoned to enquire about the invoice I received for April 2025 and understood how they billed me for April. Then when I wanted to confirm if I will still be on a pay as you go basis, i was very casually informed no, my number will be terminated as I did not specify. I remember the conversation and I was very clear, I want to keep the number and remain on a pay as you go basis. Then the arrogant person I spoke to has the audacity to tell me I did not specify. On what grounds could she tell me I did not specify? What investigation did she do to determine I did not specify? Did she listen to the recording of when i phoned in to make this determination? Then I get told I must go into a Cell C store to fix this. So, my initial instruction was ignored, I was basically told its my fault and I must rectify. Incompetence and antagonizing service I received today. I guess this is a good opportunity for me to go to another network then.......
