Security Question System is *******

I lost my phone and now want to do a sim swap with cell c. I have called 3 days in a row and I have not been able to get a sim swap because apparently I am giving the system wrong answers. My biggest problem is that I gave right answers but still told the information provided is wrong. What makes even worse is the fact that the information is communicated to an agent who then punches in the system and because we are over the phone I am not sure if the agent is has the spelling correct or whatever the case may be with the so called system. One should be able to respond to these questions personally from the so called system. The third party makes it unbelievable if they are asking the right question or even giving the right answers.
