Please stop phoning me

A lady from Mondo phoned me on Friday, saying that she's got access to my Vodacom details (SCARY!!!). When I told her that I do not have time at the moment, asking her to phone back the next week, she just kept on until I had to put the phone down. On the same day I was called again. Then on Monday I received 5 calls from Mondo! Once a lady even left me a voice mail where she was singing a song?? Very unprofessional. <br> <br> PLEASE REMOVE ME FROM YOUR DATABASE.
