HARASSMENT

I keep on receiving threatening messages from COBOL, in spite of me contacting them more that 20 times they still have the audacity to send me messages saying I owe them R3000 and that i must either pay R360 or settle R3030. i have NEVER taken out a loan from Cobol and certainly not planning to. I am NOT MS Mpofu I am Ms Phasumane. I have requested them to remove my details from their system but they keep on harassing me.
