FRUSTRATING

I have had a contract with cell c forever. Recently I was contacted for an upgrade and did do the upgrade. I subsequently changed my mind and when the courier contacted me to deliver the phone, i advised him I had cancelled and he should return the phone. I was contacted last week by cell c from the department that received the phone back. He then asked me to phone to tell c that I did not do the upgrade (laughable) I have tried to do this today and had to speak to 3 different people and mind you was being put to the fourth. My request is simple cancel the upgrade. Keep me on a month to month basis until i decide on a new phone
