Pathetic service delivery

It's a while now that I notice that my airtime start disappearing from my account. When you call cell c they always have one or other explanation as to why the money just disappeared. I had a argument with one of the consultants just now. His story was far-fetched and not believable. Yesterday I was told that I was , according to the system , on the internet while I was sleeping. My background data and auto updates is off , but my money still disappears. It's clear to me that cell c is in financial difficulty and is *****ing from their customers. I'm strongly thinking of joining another provider. It's also no use to call them regarding a problem as it's always the phone you are using that is faulty. Never their fault. Now I understand why my friends warned me about cell c. I have lost a lot of money , but hopefully it will stop when I join another provider.
