Cell C Sales Department harasses me every day!

Since last week Monday, I have been getting calls from Cell C Sales department every day. They ask to speak to Mr. Lefa Mokoena, and then I tell them that I am not Lefa Mokoena. Then they end the call.<br> <br> Every time I ask them to please change it on their system, because this number does not belong to a Mr. Mokoena, and every time they say they will.<br> <br> Just now, I received yet another call, this time from Sales Agent Siphiwe. I asked to speak to a supervisor. She said \hold"then she put me on hold until the phone cut out (about 2 minutes later) on Cell C's side.<br> <br> I have been VERY polite every time their people call me"
