STOP THE UNSOLICITED PHONE CALLS TRYING TO SELL AIRTIME

Today I get called from Mondo MTN from phone number ***. The woman who called was extremely unprofessional. She wanted to sell me something. I have no idea how MTN has my cell number. When I asked her how she got my cell number she said she didn't have access to that information. So sick of these people calling unsolicited. This is so annoying. She even dragged Vodacom into it. Saying they are calling people across all networks. She clearly knew I was with Vodacom. Do these companies cross share our cell numbers? Very annoying to say the least. But what really irritated me was the way she was trying to just plow through the conversation to make her sale. PLEASE MTN REMOVE MY NUMBER FROM YOUR SYSTEMS IMMEDIATELY. I ASKED HER TO DO THAT, BUT FOR EMPHASIS PLEASE REMOVE MY NUMBER. ACTUALLY, PLEASE CALL ME SO I CAN TELL YOU WHAT I THINK OF YOU.
