THREATEN TO BLACKLIST ME

I am receiving numerous emails from this company Loan Detector SA threatening to blacklist me and handing me over to debt collectors because they claim that I have attempted to take a loan from them on the 31 August 2017. (online). I have sent them numerous emails regarding this and telling them that i work in the middle east and i have been here for a year now and will I need to take a loan in South Africa. They insist not to listen and sends me a bill of R1276.00 fees that I owe them. This is a **** to me and this company is wanting to cheat innocent people of money and I will not let them do this to other consumers. Imagine if they did this to 100 other consumers this will be their way of cheap ********. Please be careful; of this company and I am also reporting them to other control bodies in SA so others are aware
