Money hungry parasites

In June of 2015 I cancelled my account. I kept no documents because I also left the country and returned two months ago. Since my return I've been harassed by their collectors Blake and Associates. They are telling me it is my responsibility to fix the fact that Multichoice couldn't be bothered to do their jobs properly. I must this and I must that. No respect for the fact that I did my due diligence. I'm the ******** here, guilty until proven otherwise. The funny part is that I owe them R465 when I know I had a package that cost me R740 a month. How do I owe them only a portion of that money now. Multichoice, maybe you amoebas can explain to me the math, because logic is obviously not part of your equation. You provide a service on prepaid basis, if I don't pay I have no service, so how do I owe you money for a service that you disconnected. I know you guys are obviously bleeding money because you can't compete with Netflix and is trying to compensate by *****ing unsuspecting people and then blacklisting them so they can pay you to protect their reputation. There's a special place in hell for greedy ******s like yourselves.
