***** collection company

Your company is playing funny games,I disputed a debt from Cartrack and one of your agents Puseletso Phakoe with whom I've been corresponding with has promised to come back to me with the breakdown of the amount and she's never called me back nor emailed as was the case when she asked for further documents from me,now I get threatening messages that a letter of demand has benn issued against me,is that some sick ****ing joke or what? Give me the ****ing breakdown as to how the amount ended up being as it is because I ****ing know the law too and I dont mind meeting you in a court of law,***** practices wont work here,go sort out the ****ing mess and stop threatening me with a letter of demand
