Cell C disappearing airtime

I had a problem with dissapearing airtime on two occasions, the recent one was bought on the 10th October 2023, and I realized that it disappeared today 12/10/23.

I am 100% sure that didnt use the airtime on both occasions. I blocked all subscriptions few years ago.

I called customer service on both occasions to find out where my airtime is disappearing to. I was told on both occasions that I have made a call around 18;00 on both occasions to a 068 number. I never made any call to the said number and I don't even know it or have it on my call list but I'm told that it appears on their system.

I tried to explain to the agents that I have never made any call as i buy minutes when i want to make calls but they insisted that i have made calls to a number that is not on cell c network

What actually annoys me is that they don't even see a need to investigate because there are people that i know who changed their cell numbers because they were sharing them with someone else, so Cell C doesn't think of checking things like that because they ?think they are so perfect that they cannot allocate the same digits to different people that can lead to problems.

I believe that when the same customer complains of the same problem more than once it should be investigated instead of being told that "we don't have access to your phone" and be left with your misery.

Cell C please handle customers with care and assist them when they have problems because you'll lose them.

I've been with cell c since it started but if it continues like this, I will have to part ways with them.
