very bad customer service

I called the call center last night asking them if someonehas been retrenched and she have a have aa contract with them what happens, the agent didn't seem to know his story then I asked to speak to his team leader? Who then told told the agent to tell me that she don't want to talk me, I told the agent to tell her that I am going to report her after saying this she came to then phone however with bad attitude, her name is OFENTSE MALOLE, as she said she is a team leader I was very dissapointed in her customer service, I work for home affairs customer service call center but I will never speak with a client in that manner she spoke with me last night, something need to be done.
