Poor service and communication

I was requested to upgrade the software on my phone and when the upgrade was done my cell c sim card was damaged, Cell C never informed the clients that their sim cards get damaged when a software upgrade is performed. I called cell c to do a sim swap and they advised me that i will be charged R50 for something that is not my fault. They proceeded to ask me questions that I honestly answered and the agent sounded like she is new and did not now how to do her job. Now I'm requested to go to a cell c outlet which is far so I have to use more money to get there and I'm currently at work. I'm not happy with the support I received and I hope they inform their cusotmers in the future because I cannot work without my active number which is ***. Cell C needs to communicate more with their clients and the most annoying thing is that I was not informed why I need to go to the Cell C outlet, the agent just red we received a red robot like I'm supposed to know what that means.
