Extremely poor service!!!!!!!

2 years later the request to do change of ownership has not been done. I needed to do a sim swap last week, only to find out I failed the security questions. They cannot tell me which questions were failed so I gathered that they still have not done the change of ownership. I received a reference number from Cell C on 21st November, last Saturday....I have to call them again....Stating the reference number, Penny told me that there was no query linked to the reference number they sent me. Now I'm awaiting another reference number within 48 hours....I mean really!!!!!! More than 2 years later I still have to wait 48 just for a reference number on the same query????? Where is the priority????????!!!!!!
