Poor service

I just called in now and spoke to Katiso, he tells me that he won’t be a to assist me because I was assisted last week.. the person I spoke to last week and before that told me that I should call to check if my cell c account was already updated as I had paid the account.. if I was told then I was not going even going to bother with calling, now I wasted my time and my airtime telling me that you won’t be able to assist me, why was I not told about that before that I need to subscribe, if I was told last week I was not even going I call, this is poor service
